    Question [SOLVED] GRUB Error 11: Unrecognized Device String


    OK, I apologize for having very little information on what happened. Here's what I know:

    I was running linux mint 6 on an ASUS F8SV-B1 laptop. I was browsing the internet, etc. on my bed, set the computer down on the comforter and went upstairs.
    I came back two hours later, the computer was off (heat overload I'm guessing ).
    So I turned it back on, that's when the first strange thing happened:
    Normally, in my GRUB boot menu, my linux mint entry is labeled as ubuntu, because I installed ubuntu there first, then mint, and the boot loader always kept that entry labeled as ubuntu. Now, it was labelled as Linux Mint 6. Wierd. Then when I tried to boot from that (or the option for recovery mode) I get an Error 11: Unrecognized device string. My windows xp entry still boots fine. What the heck happened do you think?

    Hi and Welcome !

    It looks like Mint's has updated GRUB and during update installation, Mint has overwritten Ubuntu's GRUB.
    Boot up from SuperGRUB CD, USB or Floppy and select 'Fix Linux Boot Loader (GRUB)' option.
    Or
    Boot up from Ubuntu CD and try to re-install GRUB.
    Open Terminal and execute this
    Code:
    sudo grub
    find /boot/grub/stage1
    Notedown values and replace those with x and y in root command.
    Code:
    root (hdx,y)
    setup (hd0)
    Type quit and reboot. Ubuntu's GRUB menu will appear again.
    It is amazing what you can accomplish if you do not care who gets the credit.

    I did all of that, I got (hd0,4) for the root, typed setup (hdo). The operation completed but nothing changed on the restart. Here's my menu.lst if that will help:
