Hey, I'm using the Boot camp assistant to partition my mac and install Windows. I have a burnt cd with Windows 7 Ultimate 32 and 64bit (I'm a student! can't afford the real Windows, for now ) When I'm choosing how to divide it, there's an Alert message that says: Boot Camp only supports 64-bit Windows installation on this platform. Please use an USB drive or DVD which contains 64-bit Windows. And this cd has Windows 7 64bit. Anything I can do?
