Alright, the problem is that I lost my Mac OS X partition. Now, all I have is Window XP with boot camp control panel on it. I have been looking around, before you guys say anything. I've seen similar posts where the solution is to insert the installation DVD that came with my MacBook pro, 10.6.3, if that makes a difference. I did exactly as the posts say, 1. Insert DVD 2. Restart 3. Hold Alt when chime is heard 4. Click on Mac OS X install DVD 5. Go from there Problem is 5, I can't go from there. The screen with the grey Apple logo and the spinning little loading thing doesn't stop, even after hours. So, what can I do?
