    Question Is there a way to install Ubuntu from a Live CD via Terminal?

    I am getting tired of the Live CD failing, I have tried 11 and 12, and it seems either I get bad media or the image is corrupt in some manner, I have gotten tired of this...

    I am looking for a way to load the Live CD, download an ISO to a second partition, and install Ubuntu straight from that ISO via the terminal. Is this possible?

    Installation/MinimalCD


    Put that on your Installation Medium of choice and try it out.

    It's a bit strange not to be able to burn a good image.

    If it gets corrupted during download, if the internet connection is so bad, installing in any way would be almost impossible because it will need to download packages over the net.

    If on the other hand, this is only a result of your burner being bad, you can try making usb stick from the image for example.

    Hi Cyberpawz,

    - Is this your first attempts with linux, or are you running an older version of Ubuntu or some other distro?

    - Have you tested with md5sum, that the download was good?

    - If the iso file is good, try Unetbootin to make a USB boot drive, if you have problems with boot CDs.

    And if you post your hardware specs, cpu, ram and graphics chip or card, it will be easier to give you relevant tips.

    Good luck

    I do it from one hard drive to another using grub2's loopmount. I used to use the loopmount from flash where my system thought flash was another drive. I have had ISO & grub booting FAT & ext4 formats.

    I think part of the issue is the new ISO are large and some software of CDs do not work with the oversize, although others do. I wrote a CD from my 12.04 - K3b and installed another 12.04 just to see how a CD works as I have not done it for ages and it just worked.

    Boot ISO from harddrive. To install it should have to be different partition or
    sudo umount -lrf /isodevice

    Basically you just install grub2, create a folder for the isos and edit a grub.cfg to loop mount the isos.

    Works perfectly, thanks. I may start using this instead of the generic CDs... seems to install faster too.

    I've been using Linux builds for a while, I am using the minimal CD only because it seems to work now. My computer can't boot from a USB stick, as much as I wish it could.

    Hopefully this will be solved soon... because I can't imagine I'm the only one having this issue.

    I think many people have problems because of poor hardware detection (often poor matching of the graphics chip or card). This is something that really needs to be improved in *ubuntu 12.04.

    I'm glad it works for you with the minimal CD

    Are you sure, you cannot boot/install from a USB drive? Now that you have a working iso file (the minimal CD).

    It might be worth looking at alternatives (in the bios menu). Sometimes a USB drive is regarded as a hard disk drive, and if you change the order of them (put the USB drive before the internal HDD), it will boot from USB. Maybe worth trying unless your computer is very old

    Another option might be to boot from an eSATA drive (providing you have SATA ports on your motherboard or that you can and want to install a SATA/eSATA card). Or if you have only IDE: boot from a second IDE drive (mounted temporarily).

    I was about to start yet "another" installation-freezing-problem thread but i will give the minimal cd a try after viewing the posts you guys made. Will be back with a feedback (hopefully soon).
