I tried to perform a triple install using Windows XP already installed, Ubuntu 9.10 Karmic Koala already installed, and tried to install Backtrack 4 Final in to the mix. The XP loader worked but the Ubuntu loader gave me an error 15, which I have corrected, but grub doesn't have the option to boot into Backtrack anymore. Can I manually add it or something in Grub2?

Using Dell Inspiron 640m POS w/ 2gigs RAM, 2ghz Intel Core 2 Duo Dual-core processor, w/ XP, Ubuntu 9.10, and Backtrack 4 Installed but floating somewhere on the harddrive.

Thanks in advance
