HP Computer with a 300 gig drive operating Windows Vista Premium. I added a secondary boot drive with Windows XP Pro installed. When I boot on the original drive, I can see the contents of the secondary drive and all operates normally. However, when I switch to boot on the secondary drive, Windows XP begins to initiate, then crashes, re-starts, begins to initiate Windows XP, then crashes. I can see a blue screen with text as it crashes, but it is not visible enough to descern what message it carries.
What causes the crash? How can I configure this machine to enable me to carry two drives, one operating on Windows XP and the other on Vista, enabling me to pick between the operating systems for various reasons... the least of which is not to use Vista till the bugs are ironed out??
