Can't boot into OS X but can boot into it Boot Camp.

[Komentra]

Hello all. I had a program installed on OS X called "Little Snitch" and I decided that I no longer wanted it so I ran the uninstaller from their site and it ran through a bunch of stuff and then asked me to restart to finish the uninstall process. So, I did and then after it turned back on it showed the apple logo on a grey background and showed a progress bar under the logo and once the progress bar finishes the computer just shuts off.

I can however boot into boot camp with no problems. I tried doing recovery but it can't unmount the drive before installing. I guess I need to go buy a disc? :/

Any help is appreciated, thanks

See if it'll boot into Safe Mode.

If not, try booting to Recovery and run Disk Utility, see if you can repair the disk.
