I want to put my copy of Windows 7 on my new macbook pro but I am coming from a Toshiba t135 satellite and it doesn't have an optical drive so it didn't come with a disc of Windows 7. Is there a way to create one from the satellite? I have a dvd writer drive that I attach USB and could burn one if there was a way to do that from my existing copy. I also have a toshiba windows vista laptop and have that copy on disc, but I really don't want to put Vista on my new macbook pro.
