Q: Command + R won't work to restart and repair my computer!

I used disk utility to repair a problem, was asked to restart using Command plus R, yet I've tried at least a dozen times and nothing happens. Help!

MacBook Air, OS X Yosemite (10.10.3), MBA 13inch 2012

    Shut down your Mac.

     

    Wait at least ten seconds then restart while holding down the Command + R keys.

    If by chance your Recovery HD is toast, then you can try this:

     

    Repair the Hard Drive and Permissions - Yosemite, Mavericks, Mountain Lion or Lion

     

    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 to the Internet Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

     

    Repair

     

    When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu. Select Restart from the Apple menu.


    The above will not replace the Recovery HD. The only way to do that is to install OS X from scratch.
