Good morning,
downloaded Yosemite from app store, then made a thumb drive to clean install it on my iMac (late 2012 27").
Installation program runs well up to the screen where it says: only one second.
But it stays stuck at this point, iMac won't reboot to start installation.

I have repaired disk permissions several times but it doesn't make any difference. Installation stops.

Help me
