I think you'll need to boot up under a bootable drive so you can run Disk Utility to fix the drive and/or reinstall a fresh copy of the OS. Do you have access the the CD/DVD that the system came with? If not do you have a retail version of the OS on a CD/DVD? Or lastly a FireWire/USB bootable HD or USB thumb drive?
