    You will have to boot your mac in OS X recovery mode and try to fix the hard disk if its corrupted by going into Disk Utility.

     

    Here, do this....OS X Recovery

     

    Repairing a Mac Boot Disk with Disk Utility & OS X

    • Reboot the Mac and hold down Command+R, or hold down OPTION
    • Select “Recovery HD” at the boot menu
    • At the Mac OS X Utilities screen, select “Disk Utility”
    • Select the boot volume or partition from the left menu and click on the “Repair” tab
    • Repair Disk is now possible, click on “Repair Disk” to repair the boot volume

     

    Hope this helps....
