The Disk Utility interface is the same one you’ll see on your Mac OS X desktop, but run it from here and it’ll be able to repair problems with your system drive. Select the drive or partition you need to repair and click the “First Aid” button.
In OS X Recovery, click the “Disk Utility” shortcut to launch the Disk Utility here. (If recovery mode doesn’t appear, restart your Mac and try pressing the keys again.) Your Mac will load straight into recovery mode.
You’ll see a progress bar appear, and you can release the keys after you do. Press and hold the “Command+R” keys while it’s booting. Your Mac will be able to fix errors on your system drive from recovery mode. From there, you can use Disk Utility in the same way. The solution is to boot into a special recovery mode. It can’t make changes to that system drive while it’s running from it. This is because it’s running in “live mode” - examining the disk while the operating system is running from it. However, in some cases, your Mac may find disk or file system problems and be unable to repair them when you perform the above steps. Ideally, that should be the end of it - especially if you used the safe mode trick above.
