I finally got 2 partitions set up on my computer. One is XP pro, and the other is Vista Ultimate.
They are both on different partitions, but now it always boots up to Vista.
How can I change it so I can choose between both OS's?
Boot with your Windows Vista DVD and select the repair option so that you could access the command prompt. Then, at the prompt, type in bootrec /rebuildbcd follow by pressing <Enter>. This operation would scans any previous installation of Windows and adds them to the BCD store of the Windows Boot Manager so that you could select which OS to boot. To change the time in which Windows Boot Manager will boot into the default OS, boot into Vista and open command prompt as an Administrator. Then, type in bcdedit /timeout <duration> where <duration> is the time defined in seconds.
in windows vista there is no boot.ini. u repair u r os from vista cd.. and detect for other xp installation...
Windows Vista no longer uses boot.ini
