My parents don't have their original XP installation discs to their dell computer and a reinstall is required as their current hard drive failed completely. My question is can i use my OEM XP installation disc to instal on a different hard drive using their 25 activation code thats on the side of their dell computer? I wasnt sure if a specific activation code is tied to each XP instal disc. Is there a legal way to get around installing with my copy onto another computer using a different activation code?
