Can anybody please tell me how to get this into a DVD. The Windows 7 I downloaded it 64 bit so that once I make a DVD I can install it on my Macbook Pro. My desktop PC is 32 bit. I have Nero so the burning part won't be a problem. I just need to know how to make a DVD out of what I downloaded or make an ISO so that I can burn it. Helppppp! I'm going crazy!
