loook at billionfold's thread in the tech forum..

he had xp, and i'm guessing it came with one of those 'free limited time upgrade to vista' coupons... anyways, he had to reformat so decided to go ahead and give vista a shot... after realizing it sucked he learned he can't reinstall xp becuase his registration codes are no longer valid...

no it has nothing to do wtih dual booting
