Ok, so I have the 20" Alum. 2.4GHz iMac, running Leopard and XP SP2 under Boot Camp. Basically, I have a few questions regarding reinstalling Windows. The way I obtained Windows was through the XP SP2b system builders OEM disc I bought. What I know about the disc is that I can only install it on one computer. However, I'm just worried about when I decided to erase everything and start a completely fresh install of Leopard and XP. Should I run into any problems when reinstalling XP? I just don't understand how the whole product key thing works and if it really is tied to my computer. Also, is there anything I should be paying attention to when I do the fresh install of XP?
