Hey, I've installed Windows 8.1 via BootCamp on my rMBP so I can play CoD Ghosts on it. Since the rMBP doesn't have a disk drive I was planning on taking disk images from each disk, and 'burning' them to some spare USB drives I have lying around (I'm not a gamer, but since when has it become OK to have games spanning 4 8GB DVD's!?). Would that work? Is there any other way, besides buying a USB DVD drive? I thought about using disk virtualization software like Daemon tools but that's not going to save me any time and means I would have to make the Windows partition very big to accommodate all the images and the actual game install.
