First order of business is to boot from your install DVD (Snow Leopard or earlier, hold down c at startup) or from your recovery partition (Lion, command-r at startup) and from there run Disk Utility to see if your disk has problems and if they can be repaired from there.

The following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot from your recovery partition (if running 10.7 or later) by holding down the key combination command-R at the chime.
try ti boot MBPro with an OS it does not support.
Advice or warning?
