Try this:


Install OS X Using Internet Recovery


Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.


Boot Using OPTION key:


1. Restart the computer.

2. Immediately after the chime press and hold down the

"OPTION" key.

3. Release the key when the boot manager appears.

4. Select the USB flash drive's icon.

5. Click on the arrow button below the icon.


Partition and Format the hard drive:


  1. Select Disk Utility from the main menu and click on the Continue button.
  2. After DU loads select your hard drive (the un-dented entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
  3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.


Reinstall OS X: Select Reinstall OS X and click on the Install button.


Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
