I'm trying to repair/reinstall XP on my Compaq but my PC never came with an XP disc. My version has a valid CD key but i've had to borrow a disc to do the repair - does it matter that it isn't the disc for this particular version of Windows? I originally had Service Pack 1, now upgraded to Service Pack 2, and the disc I've borrowed is XP Service Pack 1a. I realise that I'll lose Service Pack 2, that's not problem.
I figured I can use any Windows disc since I have a valid product key, I'd just like to make sure before I get halfway through and it all goes wrong!
