    Use Boot Camp Assistant to remove the partition and rejoin it to your OS X partition. Do not attempt to use Disk Utility for this or you will corrupt the OS X partition. Then you will have to completely re-partition the drive using Disk Utility and reinstall OS X.

    I get this error

    The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.

    You will need to do the following to restore your drive to a single OS X volume:

    Install El Capitan from Scratch

     

         Backup if possible before continuing.

     

    1. Restart the computer. Immediately after the chime hold down the Command and R keys until the Apple logo appears. When the Utility Menu appears:
    2. Select Disk Utility from the Utility Menu and click on Continue button.
    3. When Disk Utility loads select the volume (indented entry, usually Macintosh HD) from the Device list.
    4. Click on the Erase icon in Disk Utility's main window. A panel will drop down.
    5. Set the Format type to Mac OS Extended (Journaled.)
    6. Click on the Apply button, then wait for the Done button to activate and click on it.
    7. Quit Disk Utility and return to the Utility Menu.
    8. Select Reinstall OS X and click on the Continue button.
