Hi there,
Iv been using ubuntu on my laptop for just over a year now and thought it about time my desktop got the same. I cant get rid of the vista section of the disk because of things i have on there so a friend gave me a spare 80gb hard drive to have a play with it and go from there. So first of all installed unbuntu 10.10 on the hard drive alls fine i can boot into both vista and ubuntu, i then want to install backtrack 4, so i booted the backtrack disc and off we went, i split the 80gb hard drive in two and installed backtrack to one section, now i cant boot to anything other than backtrack. I got an option for ubuntu although this does look different now (showing up as 'ubuntu, with linux 2.6.35-22-generic-pae') when i go to this option i get the message "error 15:file not found"
I also have the option for other operating system, i get this message when i choose this option "error 11: Unrecognized device string"

I have googled this problem but the only solution i could find was booting with a live disc, open a terminal and type sudo grub, but this does nothing at all??

Can anyone help me please?
Many thanks Chris

You probalby need to reinstall Ubuntu's grub2 to the MBR. But to see where everything is at:
