Post installation fail El Capitan

[Alanhack]

Hi guys I finished my installation and on re starting it opens in the clover screen with the following options.
Boot mac os x from USB
Boot mac os x from El Capitan
Boot recovery from recovery HD

Whichever option I choose goes to Apple logo for about thirty secs then a circlev with line through that looks like this Ø
but in bold size of apple logo then it hangs.

Help really appreciated in advance.

I'm at the same point. If only I did not believe the guys in YouTube that install everything as it was a piece of cake... Well, my steps:
1) Did you make all the Multicast procedure?
2) Boot again with the USB disk, if your installation was good you will be able to open ElCap, the work there.
3) Always do verbose boots, it helps you (or people here) understand what is going on.
Good luck!

Eventually I removed the USB and it started its still hit and miss but it starts 4 out of 5 times. I just shut down restarted ten times eventually it worked.
