What is it you are trying to do?
Does it show for a few seconds or does it not start up at all?
Does is show for a few seconds or does not not start at all?
I am asking as I need to know if it stops you at start up or not. It does not mention this at all above.
I am only try no help
Does this show for a few seconds then proceed to boot?
If your Mac doesn't start up
If your Mac starts up to a flashing question mark but then doesn't continue starting up, try these steps.
If you don't see your startup disk listed in the Startup Disk window, close the window and try the next sections of this article.
If you don't see your startup disk
If you don't see your startup disk in the Startup Disk window, use these steps to see if your startup disk needs directory repair.
If you don't see your built-in startup disk in the Disk Utility window, or if Disk Utility indicates there's a hardware issue, your Mac might need repair. Make an appointment with an Apple Genius or an Apple Authorized Service Provider for more help.
If Disk Utility can't repair your startup disk
If Disk Utility finds issues with your startup disk that it can't repair, you might need to reformat it. You should back up any important data on your startup disk before erasing it. Erasing your startup disk deletes everything stored on it, including items in your home folder like your documents and items on your desktop.
Back up your data
If you don't have a recent backup of personal data that's stored on your startup disk, use these steps to try to back up your data.
Reformat your built-in startup disk
After you back up your important data, use OS X Recovery to erase your built-in startup disk and reinstall OS X. Make sure you select the built-in startup disk as the one you want to erase. When installation is finished, your Mac automatically restarts from your built-in startup disk.
If you're unable to erase your startup disk or reinstall OS X, your Mac might need repair. Make an appointment with an Apple Genius or an Apple Authorized Service Provider for more help.
Restore your data
After you erase your startup disk and reinstall OS X, your Mac automatically restarts and Setup Assistant appears. To copy your personal data back to your startup disk, select the option in Setup Assistant to migrate your data from an existing Time Machine backup or another disk. Choose the external drive as the source to migrate your data from and complete Setup Assistant.
It sounds like the hard-drive has failed.
What's the serial number of the MAC?
Yes, it should be on the back or the base.
C1MJ97LRDTY4 still has a avid purchase date but is out of warranty I would suggest taking it to an Apple Store for a replacement hard-drive as it looks like your HDD has failed.
