MacBook Air won’t reboot

I was working on my MacBook Air earlier when I got the spinning ball of death. I waited a while for it to go away, so I decided to turn it off and back on. When I tried to turn it back on, I heard the chime, but then nothing came on the screen. After trying to restart multiple times, I left it alone for 5-10 minutes then this came on the screen (see photo). It was flashing off and on. Has anyone seen this before and could help me get my computer working again?

MacBook Air 13", 10.12

You may need to replace the hard drive. Try these other options:


Try an SMC reset:

How to reset the System Management Controller (SMC) on your Mac - Apple Support


Try starting up in Safe Mode:

Use safe mode to isolate issues with your Mac - Apple Support


Try Single User Mode (hold command-s keys)

At the prompt, enter this command:

/sbin/fsck -fy

Press the Return key.

This will check your directory and report that it was OK or repaired. Then enter this command to startup normally:

reboot


If none of those work make a Genius Bar appointment for a free diagnostic:
