so perhaps someone can answer this before I actually this. I got a new MB and im thinking to bootcamp it just for the sake of having both OS. I dont plan to run windows but just want to have it there waiting in case I need to. So if I have my old laptop and I have the windows XP install disc with the serial code deal, can I just use that disc and password? not trying to get into an ethics debate here, I dont see it being wrong because I have already paid for the OS once.
