hey people..

i have windows xp and ubuntu on the same physical hard disk but on different partitions, what i did was i wanted to add linux backtrack to them, so i did
after i installed backtrack to them, and now trying to access ubuntu, and error comes saying file not found.

i tried to fix this by going to the command line and finding my grub by typing

find /boot/grub/stage1 and it shows that its hd( 0,8 )

so i changed it from hd(0.6) to hd(0, 8 )and tried booting, still doesnt work.
tried all hd(0,0~9) still no luck at all. its either its no such file or cannot be accessed.

please help anyone :(

You could try reinstalling GRUB from a LiveCD: https://wiki.ubuntu.com/Grub2#Recover%20Grub%202%20via%20LiveCD

Since the "find" command found a stage1 I think you still have legacy grub so I doubt those grub2 restore steps are going to help you.

The most helpful thing would be to see the results of the Boot Info Script run from Live CD as explained here:

Hi.
It looks like everything is there. I think you just need to update the menu.lst associated with the backtrack install.

Have a look here

Everything on RESULTS.txt looks correct, including the menu.lst item for Ubuntu.
My guess is that the backtrack grub probably cannot handle the ext4 filesystem used by Ubuntu.(edit: backtrack 4 is Ubuntu based and should really be able to handle the ext4 filesystem. So I' don't know what is causing your problem. Anyway: ) I suggest to use the Ubuntu Grub 2, rather than the back track grub. So follow the advice from post 3, namely boot from the ubuntu live cd and


sudo mount /dev/sda6 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Reboot. You should now be able to boot into Ubuntu, but not backtrack. To add backtrack to your Ubuntu Grub, run:


sudo update-grub

worked like a charm.
