WRONG! Vista doesn't prevent any other OS CDs from booting, which makes me believe you're just dumb instead.



XP has lots of problems with newer hardware and is an inferior OS. That's your real problem.How to change my vista os to xp?
Vista really do so. When you have a new upgraded window, then it prevent you from loading old os. SO , what you have to do is to insert the cd and check that run from cd mode is enabled in CMOS and follow on the instruction simply then.
