    Cool grub2 cannot find device on dual boot xp &10.04 , aftr update

    A little history
    I have an 32bit intel based laptop that was running xp. It blue screened so I figured it would be the perfect time to try a linux. So I made partitions (40 + 17 ) and put xp on the former and ubuntu LTS 10.04 on the second. The system worked perfectly till...

    this last update If I remember correctly was grub related. It asked me to continue install without installing something else. (I remember now there being a small checkbox which I didnt check) Anyways..I reboot and the system, wont boot either xp or linux -

    Initially it gave error unable to recongize device and gave the grub rescue prompt. I looked through the forums and tried a bunch of things
    (update, reinstall, rescatux, subergrub2 disk ). The last time it said install complete no errors. NOW it says that no such file found. I was wondering if:

    1. there is an obvious quick fix that can salvage / autocorrect this?
    2. Can I simly uninstall and do a clean install that will find the changes?
    3. I noticed (before it stopped working) that windoze add/remove list has ubuntu in its list of programs and it seems (even though I havent tried) you can remove everything like you would with a program. BUT I cant access personal files on the desktop, other folders. Hence I dont know how to back those before I nuke the linux partition
    3.5 All the files are stored in root.disk ( I figure because that is practically the only file there 8gb big, there is also swap. disk but too small) SO is there a way to open it using terminal and copy out those files?

    PLease help!

    Oh and I am pretty much a newbie. I can follow commands written here, but dont fully understand file/ installation structures hence my file paths and commands might be incorrect.

    Welcome to the forums

    In order to let us know more about your current setup, please boot an Ubuntu Live CD and post the output of bootinfoscript as per instructions here.

    Re: grub2 cannot find device on dual boot xp &10.04 , aftr update

    with my last attempt to correctly install caused this ugliness = boot/grub/boot/grub

    Code:
     => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in 
        partition #5 for /ubuntu/disks/boot/grub/boot/grub.

    You do not have a true dual boot system, you have a wubi installation (Ubuntu inside Windows).
    There have been a lot of problems after updating wubi installs lately. I'm sure googling will bring up something. Alternatively there is a wubi specialist around here somewhere and I'm sure he'll be along at some time

    You know..I suspected it all along. Even pointers to extracting personal files from root.disk so that I can try again would help immensely!

    You can access you Wubi files with the following. Your partitions are messed up but hopefully you can mount the Windows sda5 and retrieve the files:

    Code:
    sudo mkdir /mnt/windows /mnt/wubi && sudo chown -R $USER: /mnt/wubi /mnt/windows
    sudo mount /dev/sda5 /mnt/windows && sudo mount -o loop  /mnt/windows/ubuntu/disks/root.disk /mnt/wubi
    nautilus /mnt/wubi
    GRUB2

    Re: grub2 cannot find device on dual boot xp &10.04 , aftr update

    Thank you very much! I was able to extract the home directory files just fine. Some other folders/ sub folders were restricted. Any recommendations on a different partition setup? I'll try and avoid wubi if I end up reinstalling.

    Generally speaking 10.04 is long term support as opposed to 10.10 so would that be a better option in terms of sturdiness ( for a beginner looking to learn)?

    Did you ever fix this? In order to get both os's booting you need to just install the windows bootloader (run 'fixmbr' from a windows repair command line). Post back if you still need help.
