Lion installs but won't boot

[JagstangX]

I have installed Lion using a USB drive with Unibeast, but when I restart after installation (to run multibeast) I get stuck on a gray screen with an Apple logo and a cursor. I'm booting from the USB drive to get to the SSD where I have Lion installed, but that's as far as I get. Any suggestions would be greatly appreciated!

Did you figure this out? This is where I am stuck as well. Exact same situation.

I'm not certain, but I figured out that my processor has the integrated HD2000, not the 3000. I'll be installing a new graphics card next week, hopefully, that does the trick.
