Apple Logo then Reboot

[justlikeapuppet]

I'm trying to install Lion from the Unibeast USB and any time I try to boot it keeps just flashing the apple logo for a split second and then rebooting. There's gotta be something I'm missing because I've looked at countless other forum posts like this and still no dice. Maybe my motherboard isn't compatible but I really don't know? BIOS is updated to f22, which is what I need to use my CPU.

Motherboard - Gigabyte Z170x Gaming 7
CPU - Intel i7-7700k Quadcore
RAM - Corsair Vengeance 32GB DDR4 2666
HD - Seagate Firecuda 2TB Hybrid

Your hardware is too new to be supported by Lion.

I kind of figured, but I had no definite answer on this.
Any chance on the oldest OS I could use with this build? Trying to keep it compatible with Pro Tools 10/11, newest OS I can use with 11 I believe is Yosemite.

Earliest version Mac OS compatible with Z170 is El Capitan 10.11.1. Anything earlier has no support for the hardware in the kernel.
