My MacBook freezes at the boot screen
The wheel is not spinning.
I can however do the following:
- Hold down alt and select if I want to boot Mac OS X or Windows XP
- Start windows in safe mode, if I try to start windows normally the computer hangs on windows loading screen.
- Boot the Mac OS X in safe mode (what I'm running now).
What could be wrong and how can I diagnose/fix the error?
