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? Last edited by salparadise17; 01-10-2009 at 07:34 PM.. Reason: solved.

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 takes a lot of time to be a genius, you have to sit around so much doing nothing, really doing nothing. - Gertrude Stein New Users: Read This First

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.

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:

Code:
