Mac OS not selectable when booting

So after fighting with Unibeast to accept my High Sierra install for days, I finally got it to take. However, when I plug the USB into my PC and boot through my BIOS, I only get options to boot into windows and there isn’t even an icon or option to boot into Mac, even though it’s the only OS on the USB stick.

I tried installing in both legacy and UEFI mode with no success.

Specs:

I7-7700k Team T-Force 8 GB ram GTX 1070 (I’m aware of the potential issues here) ASROCK Z270 Killer sli/ac

Any help on getting Mac to show up to run an installer would be amazing.
