Okay, so yesterday night I used bootcamp to partition 40 GB to install Windows XP. Then I installed Windows XP. At the end of the install process, it restarted the computer. The problem is, when it restarted nothing happened at all. Then the computer started flashing this folder with a question mark in the middle of the startup screen. Can you help me? I've tried inserting the Snow Leopard install disc, but nothings working.
