Ok, I am getting sick OF SL screwing up and giving me beachballs, so I want to up/down-grade (however you see it) back to Leopard. Problem is I have Windows 7 installed via BootCamp with all my games, and I dont want to reinstall all that. If I reinstall Leopard, do I just install over SL or do I have to install on the whole hard drive and then reinstall Win7 and my games in Bootcamp?
