I have installed originally Windows 7, then shrunk the partition and installed Backtrack 5 on a smaller partition and logged on fine, changed the password and confirmed everything was working great. Then I installed Xubuntu on another partition (3 total so far), but the Grub 2 boot menu only shows the Backtrack or Windows as options and also when I now try to access Backtrack it says my password is incorrect? (I tried entering the one I always use and also the default, still not working)

(Note: when I installed Xubuntu after Backtrack in the setup wizard I used a different password.)

Please help me configure this. If you need more info please let me know.

I was able to reset the Backtrack 5 password by putting it in single user mode and now have root access to it but still can't figure out how to get the Xubuntu install to appear in the Grub 2 boot menu.

Logged into Backtrack 5 and opened up konsole and ran:
sudo update-grub

Rebooted and everything is showing up now! =) Just need to clean up the menu to look nicer now.
