Howto: Create LiveUSBs from Windows using a GUI (UNetbootin)

[tuxcantfly]

Purpose/Overview

This guide creates a LiveUSB (http://en.wikipedia.org/wiki/Live_USB) out of your standard 1 GB (or larger) USB flash drive entirely from within Windows, using a nice graphical application (no command lines), UNetbootin (http://unetbootin.sourceforge.net). The generated Ubuntu (or, optionally, another Linux distribution) LiveUSB functions identically to a standard Ubuntu LiveCD, so you can use it for Ubuntu installs or system recovery as you would a LiveCD, the only caveat being that your computer will need to be fairly modern (built after roughly 2002) in order to be able to boot a USB drive.

Requirements

* Windows 2000, XP, 2003, Vista, 2008, or newer (though this guide can be done from Linux as well, see site (http://unetbootin.sourceforge.net)). I have personally tested this on Windows XP, Windows 2008 x64, Ubuntu 7.10 i386, and Ubuntu 8.04 amd64; the others were reported by users. Note that this will NOT work on Windows 95/98/ME.

* A USB drive, with slightly more free space than size of the ISO file you wish to use (roughly 700 MB for Ubuntu). Your USB drive will not be formatted, so your existing files should be safe, though backup important files just in case. (The USB drive should also be formatted as FAT32 (http://en.wikipedia.org/wiki/File_Allocation_Table), though if you don't know what that is, don't worry; your USB drive is probably FAT32 unless you reformatted it yourself)

Instructions

1. Download (http://unetbootin.sourceforge.net/unetbootin-windows-latest.exe) the latest version of UNetbootin (http://unetbootin.sourceforge.net) for Windows

2. Download (http://www.ubuntu.com/products/GetUbuntu/download) an ISO file for Ubuntu (any of its derivatives such as Kubuntu (http://kubuntu.org/download.php) or Xubuntu (http://xubuntu.org/) will also work).

3. Run the UNetbootin executable. The dialog shown in the screenshot below should appear (Note that the screenshots show PCLinuxOS, but the same procedure works for Ubuntu and most other distros). Select the Disk Image radio button, and use the file selector on the far right to select your ISO file. Select USB Drive as the installation type, and select your USB drive under "Drive". Note that memory cards will also be displayed, since Windows detects both as "Removable Drives", so ensure that it's really your USB drive that you're selecting. If your USB drive is not displayed, you may need to unplug and reinsert it, restart UNetbootin, restart Windows, and/or reformat the USB drive (To reformat your USB drive, go to "My Computer", right-click the USB Drive -> Format; note that this will wipe out all data on it, and should be unnecessary).

http://sourceforge.net/dbimage.php?id=173795

4. Press OK to begin installing to your USB drive. As shown in the screenshot below, the installation occurs in 3 stages (downloading, extracting, and installing the bootloader), but since you've already pre-downloaded the ISO file, the first stage will be skipped. Since filesystem.squashfs is the largest file (over 650 MB), the progressbar will hang once it gets to this file as it is extracted and copied to the USB drive; this is only momentary, though; wait patiently, and do not close the application.

http://sourceforge.net/dbimage.php?id=173797

5. Finally, after UNetbootin installs the bootloader onto your USB drive, you will be prompted to reboot, as shown below. Reboot. You should now be able to boot and install Ubuntu from your liveUSB drive, though you may first need to specify the USB drive in the boot order of your BIOS, which can usually be accessed by pressing Esc, F1, F2, F12, Del, or another key combination which is usually displayed as Boot Devices or BIOS Setup as your computer starts up.

http://sourceforge.net/dbimage.php?id=173851

Undoing Changes

If all you wish to do is remove the Ubuntu liveUSB installation from your flash drive in order to free up space, you can simply delete the files and folders that were created by UNetbootin, which will be listed in the files "ubnfilel.txt" and "ubnpathl.txt" on the top directory of your USB drive. However, should you wish to wipe the last traces of the bootloader and liveUSB system out entirely, you can use the format tool included in Windows (note that this will wipe out all data on your USB drive); simply open Windows Explorer, navigate to My Computer, right-click the drive letter of your USB drive, and select the Format option from the drop-down menu. Accept the default options (though you may want to check the "Quick Format" option if you're impatient), and your USB drive will be wiped clean and reformatted.

Notes/Credits/Misc

UNetbootin (http://unetbootin.sourceforge.net) was created by me (Geza Kovacs). This is a simplified version of the guide I previously posted on the PCLinuxOS forum (http://www.pclinuxos.com/index.php?option=com_smf&Itemid=58&topic=46097.0), with instructions/information that shouldn't be required for Ubuntu (altering USB drive partitioning schemes) removed. This same procedure should also work for creating LiveUSB drives out of various other isolinux-based ISO files (used by most mainstream Linux distributions, such as Fedora, PCLinuxOS, etc), though it won't work for Windows CDs or the like. If you think you've found a bug file a bug report (https://bugs.launchpad.net/unetbootin), or post the issue you're experiencing.

[dubref]

Simply great utility!

It worked flawlessly. I did reformat the Flash drive to FAT32. Drive in question is a 2GB PNY model.

Before that, I had followed instructions from Ubuntu at: http://www.ryancloke.com/ubuntu-804-hardy-heron-live-usb-how-to/ and it was not recognizing the boot sector apparently and was at my wits end till I saw your post.

Thank you so much. :)

[AndyCee]

Very smooth, very cool.

Is there any way to make it persistent?

[tuxcantfly]

EDIT: This apparently doesn't work anymore on 8.04 (I last tested this on 7.10), see https://wiki.ubuntu.com/LiveUsbPendrivePersistent for instructions instead

Very smooth, very cool.

Is there any way to make it persistent?

Go to http://unetbootin.sourceforge.net/diskimg/ and download one of the files (128mb.zip, 256mb.zip, or 512mb.zip) corresponding to the amount of persistent space you want (make sure the size of the persistent disk image is smaller than the free space you have on your USB drive).

Now extract the file "casper.rw" from the zip file to your USB drive.

Now edit D:\syslinux.cfg (assuming D:\ is where your USB drive is) and add in "persistent" at the end of the line that begins with "append", and save the file, so your syslinux.cfg should look something like this:


default unetbootin
label unetbootin
kernel /ubnkern
append initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash persistent --


For more info see https://help.ubuntu.com/community/LiveCD/Persistence

Hopefully I'll get this automated in the next version or so.

I'm trying to install Hardy Server (from iso), but I keep running into a couple of problems. The first issue I have is with the CD-ROM detection. No matter what I do, it can't install drivers or detect a CD-ROM since it doesn't exist. That's the whole point of my trying this out. I'm assuming this then causes an issue with debconf since it's looking in /cdrom/preseed/ubuntu-server.seed and cdrom doesn't exist.

Any ideas?

It looks like this bug report is probably related to my issue: https://bugs.launchpad.net/unetbootin/+bug/237867

I haven't tested using any of the alternate/install Ubuntu isos, but I presume they apparently don't have the necessary filesystem drivers or the like built in into the default initrd, so it probably won't work.

You could either simply install using the standard desktop/liveCD version, remove the GNOME stuff and install the various server-specific packages.

Alternatively, should you happen to have internet access on the machines, you can use the "Netinstall" version of Ubuntu (listed under the version selection box), and from there you can select the option to download and install the server-specific packages once you've rebooted and have started the installer.

Alternatively, you could also manually give it the "hd-media" kernel and initrd files, available from the Ubuntu FTP archives, and that should be able to detect your predownloaded and extracted ISO file and install from it.

[geetarista]

Thank you for your response. I tried both the netinstall and using a regular iso, but now I'm having the same issue as people in this thread: http://ubuntuforums.org/showthread.php?t=824576. I'll post a follow-up once I figure something out.

Since the updated initrd is already in hardy-proposed, I suppose this'll be fixed upstream soon, but until then, you can download the latest kernel (linux) and initrd (initrd.gz) files from http://archive.ubuntu.com/ubuntu/dists/hardy-proposed/main/installer-i386/current/images/netboot/ubuntu-installer/i386/ and supply them to UNetbootin under the "Manual" option as the kernel and initrd files.

Also, what was the issue you encountered with the regular iso (I presume you tried installing using the standard, full Ubuntu desktop/liveCD as I suggested)?

[geetarista]

Yeah, I tried all of the options and still doesn't work. One time I got this error: "No boot filename received. DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER." I did some searching and I guess it's trying to boot from the network, which obviously doesn't work. I don't know if grub wasn't installed correctly or if it's something else. My BIOS boot settings are also correct. I don't know if this is a hardware issue or just this whole process.

I really need to have a static solution because my client wants to pay for the USB so they can re-use it to install on other servers with my instructions. So it would be best if I could use an ISO install of Ubuntu Server to make things a lot easier for them and myself. What do you suggest?

I also just tried downloading the kernel and initrd files using the manual option like you suggested and I now get the original problem where it can't find a cd-rom.

[Kpu4]

Used Unetbootin(Win) on 2 distros. After succesive write on "Flash-card" One freezes at OS load screen, second doesn`t even want to boot(freezes when trying to read data from card and shows "couldn`t find kernel" error). The distros are:

"mandriva-linux-one-2008-spring-KDE-int-cdrom-i586"

"ubuntu-8.04-desktop-amd64"

Tryed both on 2 PCs, one is my laptop, second is desktop, errors are the same. The errors about "couldn`t find/Mount" directories or files in both cases. Could it be because I use micro SD card instead of "normal" USB-Flash Drive? Any tip on solving this?

Tryed it on USB-HDD, same errors.

Could it be what Unetbootin works "better" under linux OS? )

The photo of screen with errors is here (http://img150.imageshack.us/img150/5646/mandrivascreenbv5.jpg).
Sorry for bad angles, don`t have a tripod.

when ever i try this on my 8gb usb drive

it seems to do it ok but when trying to boot using usb it just seems to ignore it and loasd the default os already on the system.

I have changed the boot order for the usb memory to boot first but still the same.

any ideas

i have tried the pendrivelinux and unetbootin same results for both

Thanks

If you've used both pendrivelinux and unetbootin, and your computer isn't booting from USB for either, it's most likely your BIOS settings. Consult your motherboard's manual, they usually have instructions for booting from various media, are you completely sure you set it up correctly? Maybe you'll have to update your BIOS if it's an older computer. If you're certain you configured it correctly, try booting the USB drive on another computer which you have confirmed is able to boot from USB, does it boot then, or does it also ignore the USB drive (if it's the former, then it's an issue with your BIOS)? Perhaps check the contents of the USB drive, can you confirm that the hidden file ldlinux.sys and syslinux.cfg exist (they should)?

@Kpu4: that's most likely because you're using a micro-SD card, and some card readers aren't supported by Linux; try again with a proper USB drive or maybe try the Hard Disk installation mode, or perhaps try installing a different distro (PCLinuxOS tends to work well).

I`m trying to install Ubuntu 7.10 on a laptop with a broken cd drive. I get the error "couldn`t find kernel /ubnkern" or something similar.
The laptop is currently running Ubuntu 8.04 but it`s messed up (my fault I just love to tweak).
It will boot from usb because I tried some manual instructions (copying the content`s of a cd onto the pendrive, putting syslinux on it, editing the syslinux.config files etc) and it nearly worked.
Should I be selecting Hard Disk on the bottom left dropdown where it says type? (I want a clean Gutsy install over the whole laptop).
The instructions at the top of this thread are for windows. Should I be doing something different from Ubuntu?
Thanks.

Since you used custom instructions, did you also remember to copy the kernel file at (paths relative to the ISO/USB drive contents) /casper/vmlinuz to /ubnkern, and the initrd file at /casper/initrd.gz to /ubninit, since that's where UNetbootin expects those files to be? It seems like syslinux, which has been configured to go by UNetbootin's default paths, is not finding them. Otherwise, try changing the syslinux.cfg to this:

default unetbootin
label unetbootin
kernel /casper/vmlinuz
append initrd=/casper/initrd.gz file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash --

Oh darn, seems like the URL changed. For the time being, just download the ISO file from ftp://ibiblio.org/pub/Linux/distributions/damnsmall/current/dsl-4.4.2-initrd.iso and specify it using the ISO diskimage option.

[efrenefren]

Why not use this link instead?
ftp://ibiblio.org/pub/Linux/distributions/damnsmall/current/current.iso

so that you will always sure you will get the current. :D

[tuxcantfly]

That one points to the standard ISO ( ftp://ibiblio.org/pub/Linux/distributions/damnsmall/current/dsl-4.4.2.iso ) which doesn't work as reliably as the -initrd.iso one since it has to locate the external file titled "KNOPPIX" on boot, rather than having everything be loaded via the initrd by the bootloader at once. I'll probably just use a few regexps to filter out the latest url to the -initrd.iso file to avoid having to update the urls.

[SAKeeler]

im having some issues with getting the drive to boot, maybe someone has some ideas.

Windows xp SP3 is the working OS for creation of the drive. I'm using a 20 GB toshiba HD in an external enclosure.

creation of the target from an ISO of the latest ubuntu seems to go fine. but when i boot to the usb drive i get:

Remove Disks or other media.
Press any key to restart.

unetbootin-windows-235.exe is being used

thoughts are welcome on what to try.
if you require more details on anything just ask.

i have tried creating the usb drive with the linux installer as well through the ubuntu live cd
the results are the same

Try booting the USB drive on another computer that you know can boot from USB; are you getting the same error? Did you also check the contents of the drive you installed to after UNetbootin installed; were the contents of the Ubuntu ISO file, and the files syslinux.cfg, ubnkern, ubninit, and ldlinux.sys (you may need to use "show hidden files" to see them) in the top directory of the drive?

[animetal]

Just to confirm with you tuxcantfly, does persistent mode work with Linux Mint 5r1?

[JR Tyner]

A few questions before I try this:

1. My USB MicroDrive has a 9GB FAT32 partition and a 3GB Swap Partition. If I install Xubuntu on the FAT32 partition will it recognize and use the 3GB Swap Partition also on the MicroDrive?

2. I have 6GB worth of Windows programs that I need to do my job and they have no Linux versions. Can I install them on the drive with WINE?

3. Will I be able to put this drive in my computer at work and run Xubuntu by bringing up the boot menu with F12?

4. Will I be able to upgrade Xubuntu, or will I need to reinstall it using a new iso file?

5. Any other comments, suggestions, hints for a first time user?

[animetal]

JR Tyner, I think you can do a normal install to your USB stick. See here (http://www.pendrivelinux.com/2008/04/14/ubuntu-804-usb-hard-drive-install/) for more information.

So far, I've only converted my USB stick into a LiveUSB distro using unetbootin and it works like a charm.

[mattisking]

tuxcantfly, Thanks a LOT for this utility. I picked a very bad time to attempt a fresh install (not primary machine so it's not the end of the world or anything) of Intrepid Alpha 2 because apparently my CD drive is dying. I downloaded the Alternate Installer (no Live CD yet - I wish you'd suppport, if possible, the Alternate Installer) and verified the MD5 of the ISO but every time I'd to an integrity check it would fail. Ultimately the CD's were fine though (tested on another machine)... the CD drive was dying. Later tests proved this out when the install puked after nuking my old partitions. Anyway, since unetbootin doesn't support the alternate installer image, I let it download and create based on the Hardy refresh. I read on the wiki that certain changes would be required but that turned out not to be the case for me. It worked perfectly! Thanks a lot!

[stangdaman]

I had a question about this. I used this software to setup the live usb stick. I went into the bios and set it to boot from the usb drive and it does. It brings up the little ubuntu loading graphic but once that finishes it just goes to a blank screen. I'm not quite sure why or how to tell what's going on. It did work with the iso on a dvd. I just need it for another PC though that I'm not able to use the cd drive on.

[stangdaman]

So, it would appear that the problem that I was having was related to the specific PC I was trying it on. I don't know why the iso on a dvd would work and not on a flash drive but it is working on other PCs and working for the one I wanted it to in the first place anyway. I just had another question though. Is there a way to make the live usb drive persistent while you're using it. Or would you only be able to do it from outside in windows or linux? I saw the instructions about making it persistent but I'm not sure if I can edit those things while it's running.

Also, if I can would it be the one labeled as "file system" that I want to extract the casper.rw to?

[tzepu]

well
i tried UNetbootin and it works like a charm
but
i need to make a multiboot pendrive (i need several distros and recovery iso's), all i want is put the pendrive into the usb port, start the computer, and choose which iso image to load
UNetbootin does that but uses just one iso at the time
is there possible to make it to put on the pendrive several iso's at once?
and to be able to choose which one to boot?
i tried to create multiboot iso(it is ok this way too) with magiciso,ultraiso,easyboot(this one is much too complicated for me,it might work if someone can explain me how to create a multiboot isowith it)
but al of them makes my pendrive getting stuck after booting at the main menu, where i have only 'default' option, and no other, and nothing works, the timer continue to run from 10 seconds to 0 again and again
when i put on just one iso, everything runs ok(i can get into livecd, install it, etc)

[sandos]

Persistance is higly needed or fedore will crush ubuntu using https://fedorahosted.org/liveusb-creator

:)

I know there is a liveusb project in launchpad, but thats not for windows, which is an important demographic for getting new users.

[moycano]

when I try with the *Ubuntu 8.04.1, during the boot I get several "Buffer I/O error on device fd0 logical block 0" warnings and the system fail to start.

Could be a distro stuff? I've successfully start many LiveUSB --> LiveUSB before (including *Ubuntu 8.04) but only with this version get this errors.

Following the pendrivelinux's tutorials, I also have the messages but the system actually start after a long wait.

:confused:

SALUDOS/REGARDS.

[minhmeoke]

@JR Tyner:
Check the AppDB on WineHQ http://appdb.winehq.org/ to find if your windows programs work in wine. Also note that UNetbootin will create a LiveUSB, so you will need to create another partition on your flash drive if you want to save changes. One last comment: using the flash drive for swap will decrease its lifespan.

@stangdaman, sandos:
A black screen after splash usually means that X.org or your graphical environment failed to start. If you are interested in persistent usb, then see https://wiki.ubuntu.com/LiveUsbPendrivePersistent

@tzepu:
Multi-boot USB is possible, see this: https://answers.launchpad.net/unetbootin/+question/24298

@moycano:
What filesystem is the usb formatted as? You can check with "sudo fdisk -l"; it should be FAT32, and NTFS will not work. Also, there may have been some kind of problem mounting the usb device, since fd0 usually refers to floppies. You could check if the usb is mounted correctly with "lsusb", and also see the error log with "dmesg" command. You could also try reformatting the drive, or checking if it has errors.

[Pyro_Killer]

Dear makers of the Unetbootin software, I have used your method to install ubuntu 7.10 on my eee pc, which I am very satisfied with. the eeeubuntu sucks, so thank you for that.

What I find dissapointing, is that the mandriva installer has absolutely NO real function, it can't install the download way, nor the ISO way.

Please fix this little, bug, beacause ther are many people out there that really needs this feature without getting all scripty

[quizwedge]

I noticed that the docs say that you can use UNetbootin to create a dual-boot system, but I can't find the option to do that. I've got a 2GB USB key that I'm trying to put BackTrack and Ophcrack on. Parted Magic too if I have the room. What option(s) do I need to select so that it makes it a dual-boot system instead of just overwriting the files that are the same?

[Natanael_L]

Yeah, I want built-in support for this.

I think that there should be a dual boot checkbox that makes two buttons appear when the user have set their options for the first OS - "Next OS" and "Done".

If the user click on "Next OS" then it should keep the settings in memory until the user click on "Done".
If the user click on "Done" before setting up a second OS, then it will work like a single boot system.
If the user click on "Done" after setting up more than one OS, then all will be installed, but instead of just installing them all one by one, the OS:es and the (one and only (no need for one per OS)) boot loader (GRUB?) will be configured so that all OS:es will be listed in a single boot loader at boot.

[vjones777]

I think that there should be a dual boot checkbox that makes two buttons appear when the user have set their options for the first OS - "Next OS" and "Done".
... boot loader (GRUB?) will be configured so that all OS:es will be listed in a single boot loader at boot.

Agreed - that would be nice. It would also be nice to be able to specify how much space to allocate to a swap partition - a FAT32 partition to be able to swap files with windoze PCs would be nice. (I'm assuming here that Unetbootin creates an extX partition as if it created a FAT partition then windoze isnt able to recognise a 2nd FAT partition on a USB stick from what I understand).

Apparently it is possible for UNetbootin to support multiple OSes, but you have to manually do that. Have a look (https://answers.launchpad.net/unetbootin/+question/24298).

[pumpin]

hi
i also have a problem with this.
after installing and reboot
i boot from the usb and there's no problem.
but after i select start *ubuntu without change ...
it loads and stops after loading the vmlinuz, and initrd.gz

it looks some sort of this

vmlinuz.....................................ready
initrd.gz...................................ready

and after that it doesn't go on so where's the problem?

[karlmp]

hi,
after installing, rebooting and changing the boot priority order in the BIOS i just get a black screen with the cursor blinking in the upper-left corner

(i have dual boot: Ubuntu 8.04.1 (messed up (i love to tweak)) and windows xp)

i just want to edit the Ubuntu and windows partitions to give more space to Ubuntu and less space to windows and then format Ubuntu to do a fresh install of intrepid ibex

[C.S.Cameron]

This is how I made a Unetbootin install to flash drive persistent.
Booted Live CD, (Live USB should also work)
Plugged in target flash drive.
Started Partition Editor
Created 1 GB FAT32 partition, (on the left side of the bar).
Created a 1.5 GB ext3 partition to the right of this, labeled it "casper-rw".
Created a ext3 partition in the remaining space and labeled it "home-rw".
Closed Partition Editor.
Un-mounted and re-mounted flash drive.
Started Unetbootin, selected Diskimage, located the iso, selected Type = USB Drive, selected correct drive letter
Pressed OK, waited 5 minutes.
When Unetbootin finished, shutdown, removed CD, rebooted.
At boot menu hit Tab, then typed "(space)persistent", (this must be done at every boot that you want persistence.
Changed desktop background, connected to wireless and installed FontForge.
Rebooted, changes were persistent.

This only works with 8.10 as 8.04 has a flaw in casper.

I'm wondering what to modify so that I don't need to hit Tab, then type "(space)persistent" at boot?

Oops missed the thing about editing syslinux.cfg in post 4.
Tried this and now I don't have to type persistent at each boot.

I sort of like home and casper on separate partitions so I can update the kernel with out loosing all my stuff.

[HereSkip]

Hi,

I've just tried to install the 8.10 x64 on my usb device and when I boot up it says

"Could not find kernel image: linux"

I have done an MD5 check on the iso and it is not corrupted.

Any ideas?

Thanks

[Timber_Wolf]

I have a few questions, as I have never done something this complicated before:

1. If I make my USB into a LiveUSB, can I then use that same USB to run the Ubuntu 8.10? (I'm new to Linux so I don't know exactly what a LiveUSB is... as in, is it just an installation function, or a full-blown OS)
2. I heard that 8.10 already has a USB creator with some sort of a persistency function. Will this work if I make a LiveUSB with this method?

I guess what I really want to know is if I can use the LiveUSB like I would a LiveCD to do this: http://www.pendrivelinux.com/2008/11/01/ubuntu-810-install-using-the-built-in-usb-installer/

By that I mean using the LiveUSB to put Ubuntu 8.10 on the SAME USB.

Thank you in advance for any help you can give me

[OBnascar]

Of course I know this is not the correct place to be posting this, but I can not find the correct place.

I was looking for a Linux Unetbootin USB install tutorial. I can not get my installs persistent and want to find out why, pretty much useless if they are not persistent.

Could some one please point me in the right direction ?

thanks,

@people getting black screens: could you post your syslinux.cfg here? Also, can you enable debugging by removing the "quiet splash" options in the append: line in syslinux.cfg? If UNetbootin does not work for you, then you can try Pendrivelinux http://www.pendrivelinux.com/ or the built-in USB creator in Ubuntu 8.10. If none of these work, then there may be something wrong with your motherboard's BIOS settings that prevents you from booting from USB.

@Timber_Wolf: LiveUSB is a usb-drive that boots a full operating system in RAM, but does not save your changes when you shut down. Persistent USB install saves your changes, but it also causes the USB drive to wear out faster due to more write cycles.

@OBnascar: Ubuntu 8.10 includes a tool to create live and persistent USBs, but if you want to use UNetbootin you can follow the instructions in http://ubuntuforums.org/showpost.php?p=6106470&postcount=38 . You should also add the "persistent" option to the "append" line in syslinux.cfg as described in http://ubuntuforums.org/showpost.php?p=5089854&postcount=4

Hi - thanks for the great utility. Really easy to use.

Hope you don't mind but I have a question on the subsequent installation that is bugging me. I have a new PC which I want to set up as a server. It has no CD-ROM installed (in the event, I think I'll buy a cheap SATA internal and use it just for the installation or use a USB external).

Anyway, I've used UNetbootin to prep up an external hard disk (USB) to mirror the ISO files and it boots up fine to the first 8.10 server menu. I select install server and the first two stages (language and keyboard selection) work fine. The third stage of the install enables the selection of the source CDROM. This isn't autodetected and the installer defaults to allowing you to select modules and devices to continue.

It ought to be easy - no module required and simply select the relevant /dev/sdb1 in my case, but the attach doesn't work. Dropping to one of the simple text terminals indicates that the mount simply doesn't work - mount -t msdos /dev/sdb1 /cdrom.

Is anyone aware of a troubleshooting guide that I can read through?

Cheers,

Martin

[Philip390]

EDIT: This apparently doesn't work anymore on 8.04 (I last tested this on 7.10), see https://wiki.ubuntu.com/LiveUsbPendrivePersistent for instructions instead



Go to http://unetbootin.sourceforge.net/diskimg/ and download one of the files (128mb.zip, 256mb.zip, or 512mb.zip) corresponding to the amount of persistent space you want (make sure the size of the persistent disk image is smaller than the free space you have on your USB drive).

Now extract the file "casper.rw" from the zip file to your USB drive.

Now edit D:\syslinux.cfg (assuming D:\ is where your USB drive is) and add in "persistent" at the end of the line that begins with "append", and save the file, so your syslinux.cfg should look something like this:


default unetbootin
label unetbootin
kernel /ubnkern
append initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash persistent --


For more info see https://help.ubuntu.com/community/LiveCD/Persistence

Hopefully I'll get this automated in the next version or so.
Are there any files for making a larger casper-rw file? Very useful btw

[thisisasignin]

Hi,

I've just tried to install the 8.10 x64 on my usb device and when I boot up it says

"Could not find kernel image: linux"

I have done an MD5 check on the iso and it is not corrupted.

Any ideas?

Thanks

Hello. I get this error as well.

I have tried Ubuntu (Hardy & Intrepid) as well as Puppy and Mint.
They all work when booting from my 8GB USB drive in a laptop.
However, when trying to use the same 8GB USB drive in a desktop, I get the kernel image error.

I do not understand why I would get the error on one machine, but not another.
Any insight would be appreciated and thank you in advance.

[minhmeoke]

@ martinveasey: What is the error message you get when you try to mount? If the system just hangs, then maybe the device is very large and mounting it takes a long time.
1) Can the system see the USB device at all, check with "lsusb".
2) Are you sure that the location that the system assigns the drive is sdb1, check "dmesg | tail" after plugging in the usb drive.
3) is /cdrom already being occupied by another device(check "mount"), or is its fstab entry somehow conflicting?
4) try creating a new mount node using "mknod", try mounting there.
Edit: there's a guide here: http://ubuntuforums.org/showthread.php?t=48126

@ Philip390: As far as I can tell, casper.rw is just a standard ext3 filesystem labelled as casper-rw, so you should be able to create it yourself with the partition editor as described here: http://ubuntuforums.org/showthread.php?p=6192609

@ thisisasignin: That is strange, there could be a resource conflict or some other hardware-specific problem. Could you post logs, if available? I'll notify tuxcantfly, the UNetbootin developer.

[mhh91]

i've used unetbootin before,but now it doesn't install the bootloader,why?


when i boot using the USB option,it ignores it and boots from my hard disk,what did i do wrong??

[shane wiley]

I installed ubuntu from a memory disk using unetbootin (the cd drive is not working too well).
Seemed fine, but after install the USB ports will not properly mount a memory stick (have tried a number of different sticks that work fine on my other computers with ubuntu). The screen will display the name of the memory stick, just not allow it to be opened.
The USB ports do 'talk to' a USB floppy drive, and do talk to printers.

[thisisasignin]

@ thisisasignin: That is strange, there could be a resource conflict or some other hardware-specific problem. Could you post logs, if available? I'll notify tuxcantfly, the UNetbootin developer.

Hello, thank you for your reply.
If there is a log available, where/how would I be able to locate it?
As far as I can tell, nothing gets written to the USB drive.
Would there be a log in the ram?

[Indycent]

Ok, I can get this to work perfectly with <8.10 desktop i386>, but whenever I try to install <server 8.04 i386> I get the following error.

Anybody have a suggestion? EDIT: I have tried formating in both FAT and FAT32... same error for both.

UPDATE:I DL'ed the <8.10 server i386> and I get the same error that martinveasey(@7 posts above) gets. It says it cannot find the cdrom. I have tried some of the suggestions of minhmeoke to no avail.
1. "lsusb" which is "not found", I assume it is not included in the limited built-in shell.
2. "dmesg | tail" the message I get:

@thisisasignin: after the error message "Could not find kernel image: linux" in my case appeared a prompt "boot:".

After this prompt I could enter a kernel file name and options. in my case worked:

ubnkern initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper

ubnkern is the kernel filename relative to the main directory of my usb stick. the same is true for ubninit, the filename of the inital ramdisk filesystem image.

The other options I got from reading syslinux.cfg in the same directory.

[thisisasignin]

ubnkern initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper


Thank you.
I will give that a try.

I created a bootable USB using unetbootin, and installed
ebuntu 2.0 iso on it.

When I boot using the USB, I get the Unetbootin screen. It has
"Default, Help & oem entries, and it counts down to automatic boot. When the count down hits 0, then refreshes the same screen and starts to count down again (same happens when I hit enter).

Any way to see a log? errors? debug it?

(Might be relevant - I first burned a CD with the same distro, when I boot it, I get the splash screen, but when I hit install, the cd spins, but nothing happens. The live cd won't start either)

Thanks,
Dan

[thisisasignin]

ubnkern initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper


After trying that command at the boot: prompt, I get

I've made a software to make a LiveUSB very easily.

You can try it out at http://usbuntu.slym.fr

It's only working with Ubuntu 8.10, Kubuntu 8.10 and Xubuntu 8.10.

Don't be afraid, the webpage is in french but the software is multilanguage (French/English)

It's really easy to use and if you are lucky you will be able to boot directly your usb key in windows through the integrated Portable VirtualBox.

Hi,

I'm trying to get a bootable/runnable openSUSE distro onto a USB stick that will persist data.

I got it installed and booting from my USB stick using the Windows UNetbootin utility, but step 3 on the website (http://unetbootin.sourceforge.net/) says "After rebooting, select the UNetbootin entry from the menu list as the system boots up", however there doesn't seem to be any option like this. The only options are:

1. Default
2. openSUSE_Live_(KDE)
3. Failsafe_Settings
4. mediacheck
5. memtest

Choosing ANY of the options runs through the usual text boot echos, but it hangs at the following:

------->Waiting for CD/DVD devices to appear...
------->Mounting live boot drive.....
------->Couldnt find live image configuration file
------->rebootexception: error consoles at Alt-F3/F4
------->rebootexception: reboot in 120 sec....

Ive tried this with 2 USB sticks, one was a 2GB Sony, the other a 4GB LG
I used the live cd distro: "openSUSE-11.1-KDE4-LiveCD-i686.iso". Is this the right one to use?

Any help for a noob would be greatly appreciated.

i've used unetbootin before,but now it doesn't install the bootloader,why?

when i boot using the USB option,it ignores it and boots from my hard disk,what did i do wrong??
I get the exact same problem.

All files are copied across correctly, but when I switch boot device in the BIOS (so that the system boots from the USB stick) nothing happens, and it ends up booting from my default hard disk instead.

UnetBootin DID work for me when I let it install files to my c:\ drive, but obviously that is not a preferred method. I don't want to be scattering stuff all over my system drive, even if only temporary.

I tried various different ISO distros, but same problem occurred every time I tried to use USB.

Plus, I have 3 USB sticks in and only the two that I DON'T want to use are shown in the UnetBootin drop list. I have to check "show all drives" to show the USB key that I wnat to use. I don't know why it only shows the other two USB devices.

sounds more like a hardware/pc issue, but try to format/reinstall see if you get any change. if no change, i'd start trouble shooting your hardware. not being able to get into your pc's bios shouldn't have anything to do with an ubuntu install.

[dmanchipman]

Humm...

So I want to try something, but I'm not sure how safe it would be, and I wanted to check first.

I want to use UNetbootin to create a partition on my Zune and use a portion of its harddrive to work as a LiveUSB.

How plausible is this and will it work? What risks do I face by doing this?

[danmarycap]

Did you also check the contents of the drive you installed to after UNetbootin installed; were the contents of the Ubuntu ISO file, and the files syslinux.cfg, ubnkern, ubninit, and ldlinux.sys (you may need to use "show hidden files" to see them) in the top directory of the drive?

downloaded the ubuntu-8.10-alternate-i386.iso and used UNetbootin to create a Live USB bootable drive. When I try to boot my Dell Mini9 from the USB (so I can install Ubuntu 8.10), I get (on a DOS-like black screen with white text):

Intel UNDI, PXE-2.1 (build 082)

(and it stops there with a blinking cursor)

or, sometimes, instead of "error loading OS", I get:

Disk error
Press any key to restart


I checked the USB drive (on my WinXP machine) and the ldlinux.sys file you mentioned is not on the USB drive anywhere.

Any thoughts?

[D_one]

I have looked at a few other places for some help here but I will try here.

I used remastersys to create a custom iso image of my ubuntu install then used unetbootin to put it on an sd card and make it bootable, works great, (the second time for me unfortunately) It is a great combo of tools to create a bootable restore of your system on an sd card.

So here is where I made my mistake: The first time around My sdb1 (sd card) was coming up under sda2 (wha t I thought was my sd card, but was actually some other file system, possibly related to windows).

Now I have a custom install of my original system (eeebuntu filesystem was originally on sda6, and is still there) and the boot loader installed with unetbootin replaced my old one that let me choose between windows and eeebuntu. Now I cant boot into either. Lucky for me, my backup version works almost as well as the original:) and I sucessfully made the bootable sd card the second time around.

Has anyone else encountered this?

So my questions:

Idealy I just want it back the way it was.
1.Can I install another boot loader that will recognize my windows (hopefull it still works since I dont have a cd drive)?

2. I cant seem to find my origina menu.lst in my original file system, is it gone? I dont see such a file in the unetbootin version, Where does it choose it's boot options? Can I edit that to my old configurations?

3. Is there any other changes that I would have to do in order to get my other two systems to be bootable?

OK, so I was easily able to boot back into windows by using partition editor to change the boot flag. However, after trying to change the boot flag to all the other partitions, I think that I erased the partition that had my boot list on it. Thus I still have only 3 options, boot into windows, boot into a live version on sd card (by holding esc) or boot to the copy of my system on sda2. So, my question is really the same, how do I either get my old menu.lst back, or edit the existing one that was installed with unetbootin to work with my system (allow for options to boot into my original system or windows).

Help, anyone?

[D_one]

And, before a reply I solved it;)

I downloaded and installed supergrubdisk and it basically found my old grub and re-installed it on the original partiition that my system was on!

I am amazingly impressed with these tools. It seems that whatever I want to do, someone has thought of and done it (except found a way for me to print on my lexmark printer which is really the only reason that I would keep xp on).

So: for all those other eee users out there or anyone without an optical drive (the netbooks are coming....)

Remastersys: a tool to create a bootable iso of your system as is now, combined with;
Unetbootin: to put that .iso on your sd card is more or less a must have. Do not choose to "show all drives" here if you sd card doesnt come up, just reformat your sd card and it should come up just fine (that was my mistake). If you do by accident replace your working os with the unetbootin version, get
supergrubdisk: put it on another sd card (or the same one if you dont need to boot into the card) and choose the install of linux that you want grub to be in.

I am now more or less completely worry free with my eee since I can always boot from the sd card into my exact system with all my tools to fix ..... almost' anything, or so it seems.

:popcorn::popcorn:my computers back baby!

Im no longer sure if these posts are relevant here, feel free to move them somewhere else if needed.

I have a Dell Mini 9 (aka Inspiron 910) running Ubuntu. I wanted to upgrade so I purchased a Runcore 32G SSD.

I cloned my original 4G SSD to the 32G SSD, using "sudo dd if=//dev/sda1 of=/dev/sdb2". When it was complete both drives had the same data on them - good start. So I swapped out the drives and attempted to boot up. The computer froze up at a black screen that said "GRUB" in the top left corner. I swapped the drives back and everything booted fine.

I had probably mistakenly assumed that if you cloned a hard drive that the new hard drive would be a mirror of the old one, only with more capacity. Wrong answer!!!!!

I did some more research on line and found that I needed to make a Live USB stick (as there is no optical drive), so I did that, making a Live USB of Ubuntu 8.04, using UNetbootin. I was to then be able to boot off the stick so that I could fix the "GRUB"

I again swapped out my drives, edited my BIOS to boot off of the USB stick as directed, and attempted to boot up. A UNetbootin screen came up that said it would boot in 10 seconds, it counted down the 10 seconds, and then came back with the message that it would boot in 10 seconds, repeat, repeat, etc. There was also a line that said "Press [Tab] to edit options". When I do that I get a line of code: /ubnkern initrd=/ubninit _

What do I do now?

Hello to all, this is my first post, and need some assistance with starting ubuntu 8.10 from my USB Disk.

My Laptop BIOS does not support booting from a USB device. So I followed this information and I am stuck.

I typed boot, but got the kernel has to be loaded first.

I am brand new to ubuntu, so any help I can get would be appreciated.

Here is an update from my last post:

I did over the iso instructions in the second link. This time I booted ubuntu from the LiveCD and ran firefox. I copied and pasted all the terminal instructions. Put the new iso image on a CD,and attempted to boot with the USB stick, and CD.

Got "Run Ubuntu using a USB Disk" hit enter, some text scroll by and finally at the end got this:

Bios EDD Facility v0.16-2004-Jun-25, o devices found
EDD information not available

VFS: cannot open root device "<NULL>" or unknown_block (8,1)
Please append a correct "root" boot option; here are the available le partations.
Kernel panic not syncing. VFS:unable to mount root fs on known block (8,1)

I tried the CD and the USB Disk on my desktop, same information I got. I decided to go into the BIOS of the desktop set it to boot from a USB device and use the USB stick alone. The USB stick booted ubuntu fine.

However I need this to work on my Laptop for when traveling. Hence why I need to get this the USB Boot CD going.

Hey all,
I have read most of this thread and do not recall seeing any mention of this, so here it goes.

I have been playing around with Unetbootin for my Asus EEE 701. At the same time, I am also trying to get Ubuntu NR to get going (https://answers.launchpad.net/netbook-remix/+question/71747) on that EEE.
After wrestling with Unetbootin since late last week, I realized today that it does indeed create a live USB drive for me, I just never get prompted to boot into it. I have to manually hit escape during the POST to select the PCs boot source. Regardless what distro I use with Unetbootin(Ubuntu 8.04, 8.10, 9.04, BT 3). I know it is not the BIOS setup on my laptops(also testing with a sys76 laptop) because when I create a live USB with the previously mentioned Ubuntu NR, it boots up just fine.

Sorry if I lost anyone, but my basic question is this: Why does the Ubuntu Netbook Remix usb stick boot up properly, yet when I use Unetbootin, I have to manually select the boot source?


Thanks all,
Steve

Does anyone have any tips on setting it up like its own install and not a copy of the live CD?

I'm trying to
create a live USB using UNetbootin and a 64bit version of Jaunty. The creation goes fine. But when I boot, I get:

loading /ubnkern
loading /ubninit
initrd extends beyond the end of memory
disabling initrd
1.224254 kernel panic. not syncing VFS : unable to mount root FS, unknown block

Any ideas??

is it possible to create multiple live linux on a pendrive using unetbootin? tried this (http://people.ofset.org/~ckhung/p/mk-boot-usb/) link but it is not user friendly for newbie like me.

Here is a manual procedure.
http://tazbuntu.blogspot.com/2009/05/multibootin-with-unetbootin.html

There are two major features missing in Unetbootin, multiboot being one.
The other one is an option not to extract ISO, unless it's necessary. For example, I'd like to have Windows XP installation ISO, can I have it without extraction?

EDIT: This apparently doesn't work anymore on 8.04 (I last tested this on 7.10), see https://wiki.ubuntu.com/LiveUsbPendrivePersistent for instructions instead



Go to http://unetbootin.sourceforge.net/diskimg/ and download one of the files (128mb.zip, 256mb.zip, or 512mb.zip) corresponding to the amount of persistent space you want (make sure the size of the persistent disk image is smaller than the free space you have on your USB drive).

Now extract the file "casper.rw" from the zip file to your USB drive.

Now edit D:\syslinux.cfg (assuming D:\ is where your USB drive is) and add in "persistent" at the end of the line that begins with "append", and save the file, so your syslinux.cfg should look something like this:


default unetbootin
label unetbootin
kernel /ubnkern
append initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash persistent --


For more info see https://help.ubuntu.com/community/LiveCD/Persistence

Hopefully I'll get this automated in the next version or so.

I made a hardy heron startup disk no problem, but when I try to get persistent mode working (as per above instructions) I get a disk I/O error in FD0 and I drop back to a shell prompt. Any ideas?

EDIT:Sorry I didn't notice the line at the top. It doesn't work with Hardy. I have now tried Jaunty. Same result.

Ok I have just about run out of options, and I'm thinking maybe there is something wrong with my hardware (??) when it comes to running a persistent live Jaunty USB.

I have tried everything suggested in this thread, and I have also gone through these:

https://wiki.ubuntu.com/LiveUsbPendrivePersistent and
http://www.pendrivelinux.com/usb-ubuntu-904-persistent-install-windows/

All yield very similar results. I can always get the kernel loaded and the first splash screen displayed. With Ubetootin, I can actually boot up in non-persistent mode.

With all the other options, or with Unetbootin after editing the syslinux.cfg file, I still get the splash screen, but after the line goes back and across the screen about 50 times, I get a black screen and an error message that says something about an I/O error at FD0.

I do know that 'fd' means floppy drive, but I don't have one, and I don't have any floppy marked as a boot device in BIOS.

Has anybody got any suggestions as to how I can get a working (peristent) live USB???

In spite of all the posts about Unetbootin (I'm a newb to Linux but I know a nice piece of work when I see it, well done), I'm still having some difficulty. I used a cruzer 2G used the box to get Linux Mint but I can't get my machine (2005 model) to boot to the usb. I can pull up the drive letter, see all the files and ISO but how do I get it to work as an OS? Net BIOS won't give me the option to boot to USB. I would appreciate any help anyone can give me on how to proceed from this point. Thanks in advance.
