Can't Boot Unibeast Installer from USB :(

Apologies for the terrible iPhone 4S quality, but it shows my current dilemma:

I have tried installing UnitBeast + Yosemite to my USB multiple times but am still getting the same error upon boot (can't get into the installer).

Any advise on how to fix this would be greatly appreciated. It has been a week without OSX now, hoping someone can be kind enough to help me out.

Thanks!

Bump? Anybody - please. Have tried everything from flashing my BIOS to reinstalling Unibeast multiple times - maybe it's something simple?

Thank you,

First thing I would do if my USB didn't boot would be to rebuild the stick and/or try to see if it can boot on another system.
