Ive wanted to use bootcamp so that I can install Windows 7 on my macbook, but after the installation, it has come to my attention that you will need a Mac OS X install disk to complete the whole bootcamp setup. I recently got the new MacBook Air 13 inch that just came out, and it didnt come with a disk, nor was I given the chance to purchase one. Can I do this whole process without having the purchase an OS X disk for no reason? I an running Lion version 10.7 Any help is greatly appreciated.
