I have a 2.0 Alu. MacBook and it was fine this morning everything was working, I decided I wanted to play CoD so I switched to my Windows side. Everything was working as well and then I decided I wanted to use Leopard again. Thats when I noticed I couldnt use my mousepad and the keyboard wasnt responding. A Mac "Genius" told me to reinstall Mac OS X through Bootcamp but how can I do that?
