Okay. If there is a FAQ on this somewhere, please feel free to hunt me down and smack me upside the head. I'm thinking of upgrading to Snow Leopard, and using Bootcamp to install Windows XP on my Mac. I have 57gb of unused hard drive on my Mac. I know the basics, i.e. how to partition my hard drive, how to install XP with Bootcamp etc, but there are some things I'm unsure of, and I can't seem to find the answers I'm looking for. (I probably just haven't looked hard enough). Okay so, questions: 1) How do I keep from losing all of my files when I make the transition from Tiger to Snow Leopard? 2) I want to install a game on the Windows platform. I'm thinking of using a 30gb partition for the Windows installation. How will this affect computer performance when I've transferred all of my files back onto the OS X partition? 3) Can I boot the Windows OS from an external hard drive? 4) Would purchasing a large hard drive make this task easier, or would that be unnecessary? If any of these questions are answered elsewhere, then I'm sorry for wasting your time, and would appreciate a nudge in the right direction. Any help would be greatly appreciated.
