Hi there,

Try booting into Safe Mode.

If Safe Mode does not allow your system to boot, then the problem is deeper in the OS configuration and drive setup, and the most likely cause is a faulty hard drive.

Try booting from an installation disc and it should allow you to run a repair on the hard drive if it is not completely failed.
