Ok, I have a 2.16GHz 15" MacBook Pro, and I don't really want to use up hard drive space with Windows and BootCamp. However, I've got 2-3 unused external drives sitting around, so, my question is: Can I plug an external drive into my MBP via USB, install Windows via BootCamp on that and be good to go? How does that work? :\ edit: Let me rephrase. I have games and a few apps that require Windows to run, that I need to run on my MacBook Pro, and I have a USB external drive to put Windows on. How do I do it?
