No grub after installing ubuntu 10.10 windows 7 just starts

[ubunewbi]

Hello everyone and thanks in advance for any help, I have just installed ubuntu 10.10 onto my daughters laptop that is running windows 7 ultimate.I did the installation from a live cd and the process seemed fine, after installing the disk tray opened by itself and the pc restarted. But instead of the grub cumming up it went straight to windows 7 and did a chk dsk. I put the live cd back in and rebooted, looked at partitions with gpart and the ubunntu partitions are there. I then tried to install grub from the cd but when i looked for it in the terminal by entering sudo grub it says "sudo: grub: command not found"


So I think ubuntu is installed ok but for some reason it didn't swap the mbr with grub. I used the same live cd a week or so ago to install on my desktop and it worked fine, should I use the windows disk to erase ubuntu and expand the space back into windows, burn a new disk and start over otr is there another fix?

Please help

Click on the bootscript in my signature and run it. Come back to the thread hit the reply button then the # in the reply panel and paste all the text from the generated file from running the script, between the code tags.

Actually I think you will like this script as it answers the whats in the MBR amongst other relative questions.

there is the info you asked for I hope it helps, the disk has a few scratches on it could that have caused the problem, I don;t think it is since i used it a few weeks ago on my desktop and it worked fine. the desktop has xp on it tho. Is it something in win 7 that's trying to stop the duel boot?

thanks for your help

So two things MS is still in the MBR, and the grldr. I'm not real confident with the glrdr as far as helping you, but there are others that are. Everything looks okay in the script, but it is easy to miss something. Lets hang for the pro's on this one. If glrdr wasn't there I could help but I am hesitant here.

If your going to be up for a little while check the thread as about this time and later regulars show up that may have the answer;)

see the next post

[oldfred]

Ubuntu thinks it is on hd1 and your windows install is on hd1 or sdb. But your script shows hd0 is the only drive. Did you install from a flash drive that the system saw as sda? If so it installed grub to sda the flash drive that you do not have in system now. If you plug in flash and boot it, it may boot Ubuntu.

You need to install grub2 to sda or the 250GB drive. But if you plug flash back in, then the drive number may change so we need to verify drive.

#Install MBR from LiveCD, Ubuntu install on sda5 and want grub2 in drive sda's MBR:
#Find linux partition, change sda5 if not correct, and/or even sda if sdb wanted:
sudo fdisk -l
#confirm that linux is sda5, if sdb5 change every a to b.
sudo mount /dev/sda5 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda
#If that returns any errors run:
sudo grub-install --recheck --root-directory=/mnt/ /dev/sda

I know it has me baffled as well, shouldn't those have been deleted and replaced with grub? Thanks for trying to help, and I will check back later. Do you know if the same problem happens with 10.4? If we can't get this working maybe I will have to scrap this and go that route.

Thanks again

oldfred is correct or at the least I would trust them. With grub it is just making sure when your installing; in that install gui set is a grub goes to dropdown. In Maverick I believe it is in the custom partition area, earlier versions like Lucid it is a advanced button on the last gui in the install gui set.

[ubunewbi]

OMG oldfred your a genius, I think i figured it out, my laptop has a 1gb ram and I use a 2gb sd card to boost the ram in windows using ready boost, I bet that during the install it tried (or wrote ) grub to the sd card, thus leaving the windows boot loader and causing the problem. Oldfred you know much more about this than I does this sound plausible? The problem is that the bios will not let me boot from the built in card reader (at least i don't think it will). Is there a way to fix this or should i scrap the partitions (ubuntu) and start over?

and yes it did see the card as a hard drive i had to switch it from the card to the hdd

I have removed the sd card,

how do i install grub and fix? I am very new to this and would appreciate it if you could walk me through it should i do a print screen of the partitions in gpart?

Thank you all 4 your help oldfred you are a genius u are making all the bricks fall into place.

[wilee-nilee]

This is easily fixable, you just need to boot the live cd you installed with and look at oldfred's post.

The command in his post
sudo fdisk -l
will probably identify the HD as sda probably from a live cd so ask more questions if needed. I say probably be sure to run it before the commands to just get orientated.

[ubunewbi]

I am running the live cd now , but I don't really understand the instructions on loading grub, when i open a terminal and type sudo grub it says its not found

file:///tmp/moz-screenshot.pngis there a way 2 attach a screen shot

You dont run a sudo update-grub until you get into the actual install.

Run this command in the terminal and post the output.

sudo fdisk -l

just copy and paste the command to the terminal we are just making sure we have the HD identified and the partitions

[ubunewbi]

i have removed the sd card so it won't cause any more problems

[Quackers]

That should be sudo update-grub :-) but as grub is not yet installed to your HDD it probably won't do any good.
If you use oldfred's commands one at a time in the terminal (Applications menu > Accessories > Terminal ) grub should load fine.
I'm not sure whether the grldr (which is the grub loader from an earlier form of grub) will do any harm, but I'm sure it can be removed, if necessary, from within Windows.

[wilee-nilee]

Here are oldfreds actual commands this part I know;)
first in the terminal run

sudo mount /dev/sda5 /mnt
then in the same terminal

sudo grub-install --root-directory=/mnt/ /dev/sda

#If that returns any errors run:

sudo grub-install --recheck --root-directory=/mnt/ /dev/sda

Reboot to Ubuntu and in the installed Ubuntu run.

sudo update-grub


Quackers is correct.;)

[ubunewbi]

It said installation finished no error reported. Is that it, is it fixed? Just wanted to make sure before i restarted. If this is the fix I will be so happy.

Again thanks to everybody for helping. I have seen a number of similar problems and I am wondering how many are caused by cards that r being used for ready boost, I totally forgot the card was even in there

Duh I need to read more before I reboot though I have a question will i need to reboot using the live cd? I am assuming no but well you know what happens when we assume. and I would rather be safe than sorry

[wilee-nilee]

Yeah reboot and you should see grub go to Ubuntu first, open a terminal and run.

sudo update-grub

That should be all you need I think.;)

Hard to say about the card, just watch for that where grub goes whenever you install. The grub point to the MBR is in the install gui's

[ubunewbi]

I rarely say your welcome but your welcome, thankfully oldfred was on I thought loading grub was not a problem, but you just never know.;) Of course Quackers support is helpful to all of us.

[Quackers]

Very nice :-)
Just as a check, make sure Windows boots ok, but I suspect it will as W7 seems more robust than previous versions.

[ubunewbi]

Again thank you guys, my daughter will be so excited in the morning she loves using ubuntu on the desktop and was so bummed it wasn't working on her laptop.

Windows loaded perfectly

You guys are awesome!!
Thanks

[oldfred]

Glad it worked.:)

You guys were working late ( at least on Chicago time).

I am somewhat interested in the flash drive that you were using as a ready boost device. It sure looks like the system sees that as a hard drive as grub must have installed to it as sda. Grub defaults to sda unless you tell it otherwise and for whatever reason Maverick only gives you a choice on where to put grub if you use manual install.

If you plug flash back in and in BIOS or one time boot key choose which hard drive to boot will the flash show up (it still should have your bootable grub in it.)?

My USB flash drives show up as hard drives. My multicard reader adds drives but my hard drives remain first, so I do not have drive order issues. I have had flash drive order booting issues but that is another story.

[ubunewbi]

It's a SanDisk Ultra 2, 2GB, 15/MBS transfer rate sd card ( not usb flash/thumb drive )
and yes there was a bootable grub on the card.

It does show up on Gpart as /dev/mmcblk0 as a partition on the drop down list in gpart in the upper right of the interface

I have read other posts where grub did not load and I bet a good percentage had a sd card in while doing the installation of Ubuntu, This computer used to have Vista on it and with Vista being such a ram hog I had little choice but to expand the ram using ready boost, I used the card because it fit into the machine and didn't stick out like a thumb drive does. Since it is in there all the time, I didn't even think that it would cause a problem, as a matter of fact I had to change it from the card to my hard drive when doing the install.

If you catch another post about grub not loading with the installation of Ubuntu as if they had a card in when installing I would be curious to find out.

Hope the info helps and if you need more info just let me know :D

Again thank you for the help Oldfred

[oldfred]

Thanks for the extra info. One more thing to watch out for on issues with booting.

I have seen a lot of issues and even when I installed to a flash drive from a flash drive and removed the install flash drive order was different enough that it would not boot even by UUID. Once I fixed drive number it worked just fine.

[devil_me]

Hello, I just installed Ubuntu and running it. I wanted to have windows xp, 7 and ubuntu on my 1tb hdd. I installed xp first and then seven and ubuntu at last in different partitions. The problem now is the grub seems to have replaced my windows boot loader. The menu shows windows 7 loader but when I hit it it returns to the grub boot menu. Please help with this and thanks in advance for any help. I have run the bootscript file provided by wilee-nilee. here is the output I got.

devil_me, It would have been better to have started your own thread. This is solved so not many will look at it.

You have installed grub2 to the windows boot sector in the windows sda1 partition. Windows has to have its code there.


sda1: _______________________

File system: ntfs
Boot sector type: Grub 2
Boot sector info: Grub 2 is installed in the boot sector of sda1 and
looks at sector 163430648 of the same hard drive for
core.img, but core.img can not be found at this
location. No errors found in the Boot Parameter Block.
Operating System: Windows XP
Boot files/dirs: /boot.ini /bootmgr /Boot/BCD /ntldr /NTDETECT.COM


Fix for most, a few have other issues, better than windows fix in many cases as it also fixes other parameters:
This has instructions on using testdisk to repair the install of grub to the boot sector for windows from Ubuntu or Linux LiveCD.
http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Boot_Sector

Also if you install more than one copy of windows, window moves all the boot files from the second install and only boots thru the first install (the one with the boot flag). Grub then will only show the one windows as bootable.

To get each MS to have its own boot loader make a second primary partition and set its boot flag on, then install the 2nd product in it. Multibooters, Pictures here worth 1000+ words
http://www.multibooters.co.uk/multiboot.html
A user who installed two windows & it worked to boot from grub directly
http://ubuntuforums.org/showthread.php?t=1271600

You still have windows in the MBR and need to install grub to the MBR.

Reinstall grub2 - Short version
https://help.ubuntu.com/community/Grub2#Reinstalling%20GRUB%202
full chroot version:
https://wiki.ubuntu.com/Grub2#Recover%20Grub%202%20via%20LiveCD

#Install MBR from LiveCD, Ubuntu install on sda5 and want grub2 in drive sda's MBR:
#Find linux partition, change sda11 if not correct, and/or even sda if sdb wanted:
sudo fdisk -l
#confirm that linux is sda11
sudo mount /dev/sda11 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda
#If that returns any errors run:
sudo grub-install --recheck --root-directory=/mnt/ /dev/sda

Note that the install device is sda not sdaX where X is a partition number. You want grub in the MBR not in a partition.

Click on the bootscript in my signature and run it. Come back to the thread hit the reply button then the # in the reply panel and paste all the text from the generated file from running the script, between the code tags.

Actually I think you will like this script as it answers the whats in the MBR amongst other relative questions.

=======Devices which don't seem to have a corresponding hard drive==============

Im having major issues with grub and grub2 after switching from Arch linux. Can anyone please help? Im in a live CD right now and everytime I boot from the linux drive it just shows up at the grub prompt. I tried mounting the drives and using:

sudo grub-install --root-directory and it just hangs there saying: Probing devices to guess BIOS drives. This may take a long time.


I'll give it more time but, maybe I'm missing something? Any help would be greatly appreciated!
