Q: Mac Book Pro (2012) tion not booting after installing boot camp

On Sunday I installed windows 8.1 on a partition that I made using boot camp assistant. It worked fine after I installed windows yestarday. Today when I turned on Mac Book Pro and booted it up from the OSX Mavricks partition it turns on but after I hear the start tone, I see the apple logo, a progress bar and then a couple seconds later I see the spining gears and  then my computer shuts off. I tried booting the computer up from the windows partition and that worker fine. I tried booting it up from the mac OSX parttion and same thing again. I tried pressing Comand R on start up to go to disk utility so I could verify the Machintosh HD disk. It said that it needed to be repaired but when I went to  go  repair it I get an error message saying " Disk Utility Cannot repair this disk... back up your files." Next I try going in to single user mode and I type /fsck -y this does not work either. I tried booting into safe mode but that did not work. What should I do next?

MacBook Pro, OS X Mavericks (10.9.4)

    Hello Jack Ryen,

     

    Thanks for using Apple Support Communities.

     

    From your post I see that your Mac will not start up in OS X, and the result of you verifying the disk indicates you need to back up your files and reformat.  As Disk Utility states, the next step for this issue is to backup and if possible reformat the drive.

     

     

    Important: If Disk Utility is unable to repair the internal drive, you should back up your important data immediately and if possible, reformat the drive. Consider bringing the Mac to a Genius at an Apple Store or an Apple Authorized Service Provider for further diagnosis. Be sure to ask that, if the drive needs reformatting or replacing, they contact you about escalating your case to a special data recovery service. If you plan to visit an Apple Retail store, you can make a reservation (available in some countries only).

    Every indication (including seeing a progress bar at Startup) is telling you there is a serious problem on your Hard Drive. The conventional recommendations see the Drive as the prize, and suggest you re-initialize it to salvage the drive.

     

    With drives now selling for well under US$100, the drive is expendable. Your data is the prize. If you have a Trusted Backup, congratulations, you are doing it right. If not, let this "near death experience"  convince you that an external drive and a Time Machine Backup is a requirement, not an option.

     

    A drive 2.5 or more times the size of what needs to be backup up is recommended. USB-2 is perfectly fast enough for Backups.

     

    ------

     

    To get out of this mess, I recommend you buy a new drive that could replace your current boot drive, and an external enclosure to hold it. Once you install a new copy of Mac OS X on this external drive, you can boot from it and bring the full power of Mac OS X and additional Utilities such as Data Rescue to bear on data recovery. At you leisure, you can decide whether the old internal drive is still good by writing Zeroes to every block using Security Erase function of Disk Utility.
