Cannot turn on MacBook Pro after installing macOS Sierra beta

Tried installing the beta for macOS Sierra on my MacBook Pro. Installation seemed to be going through fine, until restart, now when I log in, I see code pop up in upper left hand corner, briefly, then I receive an error message (in multiple languages) stating, " Your computer restarted because of a problem. Press a key or wait...".

Now I am unable to use MacBook Pro. Any suggestions would be greatly appreciated!
