I really have no clue about how to install a harddrive. Im not looking at a simple plug n play... here is what I am trying to do. I am building my own computer and I am buying a new harddrive. I want to install XP Pro on it. Can I just plug it up throw in the XP Pro cd an install or is it more complicated then that? Then if I want to copy games or if I can office to it from my hardrive now which has XP Home on it, can I do that, if so how?
