If your Mac doesn't start up

If your Mac starts up to a flashing question mark but then doesn't continue
starting up, try these steps.

   1. Turn off your Mac by pressing and holding the power button for a few
   seconds.
   2. Press the power button once to turn your Mac back on. When you hear
   the startup sound, immediately press and hold the Command and R keys on
   your keyboard to start your Mac from OS X Recovery
   <https://support.apple.com/kb/HT201314>. Keep these two keys held down
   until you see an Apple logo or globe appear.
   3. If prompted, select a Wi-Fi network to connect to the Internet as
   part of startup.
   4. After the Recovery screen appears, click the Apple menu and choose
   Startup Disk.
   5. Select your startup disk, then click Restart.
