Hello all, I am pretty sure the question belongs in this thread. I am installing a new hard drive for a friend, which I know how to do just fine. This is the first time I am not adding a slave though, he needed more memory, we backed his old one up and all that, I will convert that one to a slave but when making his new hard drive the primary, I need to install XP. Of course he does not have is XP disc so here is my question, I have a disc with an image of XP and I also have my XP disc. If I were to use either disc, I would just need his key, which we have, to install windows and have it legal right? Side question, is this the same for all Windows OS's? Thanks in advance!
