I installed Ubuntu 7.10 to an existing install of Win XP Pro in a dual boot.
Everything was working fine. Each OS is on it's own drive (small 80gb
SATA's). The Grub Loader would bring up the OS's and it worked fine.



Yesterday, I wanted to install another distro and put another drive into the
machine. This 3rd drive is an IDE drive, also 80gb that had a Win XP Pro
install on it. Using GParted, I cleared the Windows install so now it's
empty.



Problem is that I can get the Grub loader to show the OS's in the machine
(Ubuntu, XP Pro) but it will not boot into the Ubuntu from the loader. Win
XP works fine from the loader, but not Ubuntu.



I've run the Super Grub disk and tried to change some commands but I must be
doing something wrong as they are not being saved.



I can't believe this is much more than telling Grub where to find Ubuntu. Am
I wrong?
