Hello everyone, first post hurray. Anyway, I am considering purchasing Windows 7 to install on my new macbook pro with boot camp. My friend gave me a copy but it's on a DVD-R and I don't want to mess with that. Regardless, I want to play my games on my mac and purchasing a copy of Windows 7 seems to be the only solution. I have no previous Windows OS on my mac, and was wondering if Boot Camp will allow me to install a discounted upgrade version of 7 on my mac? I don't have a lot of money, as I am a student and bought a computer on lay-away, so I am looking into this. It is 30 dollars so Thanks for any input/help!
