I have a MacBook Pro that's refusing to boot to OS X (just see the Apple logo and an infinite loading spinner). When booting, I hit ALT to bring up the drive selection screen (split between my Mac and Windows partition). If I press and hold C on this screen a CD option appears. However, when attempting to boot from the CD the mouse freezes and the system appears to lock-up. I'm trying to boot the OS X Install Disk 1 to do a full system format and reinstall with no luck. Can anyone help?
