Turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.


If the recovery startup above doesn't work, the hdd may have failed and the recovery partition cannot be used.


IF that's the case, then try one of these startups to access internet recovery :

  • If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
  • If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available.
