    Can you post the result of this Terminal command here?
    Code:
    diskutil list

    Have you tried repairing the disk (the one at the top) in Disk Utility?

    Typically this means directory problems or disk problems. It is also possible that this is a result of a failed install. Your best bet is to check the disk with SMART Utility or some such, and make sure your drive isn't failing. If it isn't then you need to examine the volume in terminal and see if you have a failed install. You can also try verbose mode at boot to see where the system is throwing the prohibitory sign.
