so i get a free windows 7 download from my school and i'm trying to install it on my MBP. couldn't get it to work, but i do have the registration code, so i downloaded a .iso of Windows 7 Professional. boot camp isn't recognizing it though. what do i have to do so that boot camp will recognize it as the Windows 7 setup? i've tried burning the .iso to a disk, that didn't work. also tried mounting the .iso on the desktop and burning the contents to a disk. that also didn't work... total beginner at this, please help!
