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?
