Power failed and now iMac trying to reboot several times

Continuous power failed and computer try to restart Gets the part of the journey through the bar on the screen, then restarts.

-iMac 27 "equipped with the latest system and all software are uptodate.

-All the devices are disconnected.

-Tried to hold down option, also I tried shift key and no change in the attempts to restart.

-Unplug the power cord for a few minutes, but no help.

Any other suggestions?

Try to do a reset of the PRAM, if this does not work try starting on the (command-R) recovery Partition at startup and run disk utility - repair disk. If errors appear on your hard drive is damaged and must be replaced.
