OS X Yosemite - Beta 6 - Won't Boot

[Oliver G]

Just installed Beta 6, and now it won't boot. It gets around half way on the boot screen before stopping. It has been like this for over an hour. Any suggestions? I have reset PRAM.

I am using a Mid 2012 MacBook Pro.

I have to go out now, so I have just let it sit on the boot screen. Hopefully when I get back it will have booted.

Has anyone else had this problem, and if so what did you do to solve it.

honestly it sounds like a corrupt installer.
