I have a 400gb IDE drive and a 500gb SATA drive. On the 400gb IDE is my installation of Windows XP Pro. I decided to put Windows Vista on the 500gb drive to play around with it. I got bored with it after a while and wanted to give Ubuntu a shot for a while, so I installed it over Windows Vista on the 500gb drive. Now when I boot it goes through the GRUB boot menu then it goes to the Vista boot loader screen then I have to select Windows XP (It's actually something like "An older installation of windows" or something like that). I had bought a new case and moved everything over to it. I did NOT change anything, and now when I try to boot it takes like two to three times longer, and I cannot get to the Vista boot loader to boot to Windows XP Pro, so I am stuck in Ubuntu. I really don't want to reformat the 400gb drive with XP Pro again, so is there anyway that I can fix the XP Pro boot? (I don't care if I have to get rid of Linux, I just want my working copy of Windows back...)
