Hello, I have a macbook pro running snow leopard with windows 7 on bootcamp. I've had this computer for three years and it's starting to get a bit slow and buggy, I'm going to university in a week and a half and before I go I want to perform a clean install of snow leopard, upgrade it to mountain lion and to reinstall windows. By reinstalling i mean starting over again fresh by formatting the hard drive etc. Can anyone tell me the easiest way to do all this? I have the snow leopard and windows 7 discs. Thanks.
