Well I just hosed my registry and so am doing a clean install. I'm going to make a seperate OS partition this time . I would just make it 5gb to be safe, but I want to conserve my valuable speedy raptor storage because I know I will eventually end up filling this drive. What is a reasonble size for a Windows partition? I don't want to come within a hair of the minimum, I just dont want to waste a whole gig or something. I'm thinking 3 or 4 gb? Thanks!
