This symptom occurs when your Hard Drive is too damaged to mount. Your Mac runs the equivalent of Disk Utility (Repair Disk [directory]) and shows the progress bar as it works.

-- If your disk is fixed in one pass, Booting will continue normally.

-- If your disk can not be fixed in one pass, your Mac may power off or attempt to continue and reboot endlessly, or crash and halt.

Solution:

You should try to boot to Recovery Mode, and launch Disk Utility. Select "Macintosh HD" Volume, and ( Repair Disk), do this again and again until no problems are fixed, or it gets stuck doing the same thing each time.
