Couldn't allocate runtime area - Trying to install from usb

X99 motherboard, nvidia GTX 1070 graphics card, intel cpu, I'm installing through UniBeast. I've had various errors. The prohibition sign, the freezing at the apple logo, the "this version of mac OS X isn't supported on this platform", but it's usually "couldn't allocate runtime area".
I'm still at the stage where I try to boot from a USB drive for the first time.

Thoughts?
