Q: OS X el capitan hangs during reboot

I had just upgraded to El Capitan on my 27" late 2013 iMac. Then I had a power outage. It will not boot, not even in Safe Mode. Even when I turn it off by holding down the power button and restarting with shift key held down, it shows about 80% progress on the startup screen (it doesn't start from the beginning but starts right there) and I can't get it to launch into recovery mode or safe mode. What are my options?

boot into AHT mode and check your HD

if the drive appears to be functioning properly turn off file vault and see if the load time is better.
