When you ask about not needing a new copy of the OS, can we assume you are talking about a new hard drive in the same computer? If so, you are probably okay. If you are talking about porting everything from one hard drive to another that will wind up in a different system, the answer is probably not. You would need the OS CD for the many different drivers, at a minimum.
