I recently got a macbook pro, and just got windows 7 for free from my university (want to be able to play windows games). The IT guy there said I would need to install it once, then install again using the registration code. I installed it once (without using the code), and Windows seems to be running fine. Now I know bootcamp tells you to use the windows driver disc that comes with the macbook, I just wasn't sure what to do first (or if at all). Do I need to go through bootcamp again to "upgrade" windows using the same disc as the first install? Or do I simply need to use the disc that came with my laptop? Or both/neither? Thanks for any clarification.
