Dual boot system starts xp only
 

I have working Vista on one drive, working XP Pro on another. The system will only boot XP. It does see the Vista drive. The only way I can boot Vista is by putting the Vista DVD in the drive and booting that way.

Help? How can I set up a dual boot system when XP only boots.

Bios is no help. I cannot select a particular drive there.

Use a boot manager like EasyBCD.
