Did you use Recovery HD to do that or single user mode?

single user mode
Expert:  Mike replied 2 years ago.

Try Recovery HD. Reboot into the Recovery HD by holding the power button for 10 seconds then startup and hold down the ‘Command’ + R’ keys on the keyboard during the start up process. When you see the Apple Logo you can let go. When the machine boots you may have to choose your language then you will see the OS X Utilities screen. Select the Disk Utility and then select Continue. Then in Disk Utility select Macintosh HD in the left column (if there are two with that name or it is named something else choose the first indented item) and then Highlight your hard drive and on the right select the First Aid tab if it is not already selected, then click on Verify Disk on the far right. If that says “OK” in green type then select Repair Disk Permissions. If it is not ok let me know.

Please stay on this question... if the Disk Utility procedure is ok then quit Disk Utility and select Reinstall Mac OS X.
