You may have got accustomed to seeing an Apple logo every time you restart your Mac. But, this happens only momentarily. After the Apple logo, you are directed to the desktop or account login screen. If the gray screen displaying Apple logo seems to remain there forever, then it is very likely that your hard drive is corrupt. A range of other things can cause your Mac to get stuck on this startup gray screen, such as issues with peripheral devices and incorrect system software settings. You need to do a little troubleshooting to get past this issue and regain access to your data.
Fixing Issues with External Devices
If there are external devices connected to your Mac (such as printers, USB hubs, and hard drives), you must test these devices immediately. To do so, you can plug out each device one by one, shut down your Mac, and then try to restart. If your Mac boots without any issues, then the culprit was the last device that you removed from your system. You might have some luck with this trial and error procedure.
Try Booting in Safe Mode
Booting your Mac in Safe Mode will automatically resolve a range of issues. Safe boot does a good job of running system checks and repairs while not allowing the OS X to load any startup or log-in items. If the Mac starts without any issues, shut it down again and attempt to restart. If the system freezes on gray screen again, you should try to reset the PRAM and NVRAM. These two sections of RAM deal with power settings and internal systems settings.
Resetting PRAM and NVRAM
To do this, you need to shut down your Mac. Restart your computer while continuously pressing these four keys- Command, Option, P, and R. You need to ensure that they are help down before the gray screen is displayed. Keep pressing these keys until the startup chime is heard twice. After the two chimes, release these keys. If your Mac starts this time, then the problem is resolved.
Repair Startup Disk with Disk Utility
If the directory of your Mac OS X startup disk is corrupt, you may experience boot issues. Apple's Disk Utility performs directory repair on Mac. To do this, you need to boot from your OS X Install disc and run Disk Utility to repair your startup volume.
If your problem persists, take help of professional Mac data recovery software to reclaim all the lost files. These software come with a Bootable DVD that can be used to boot your Mac and perform data recovery. Furthermore, they support the latest Mac OS X 10.8 Mountain Lion.
