Trouble booting from partition and using GTX 1070 (10.12.5)

I have all bios settings set to what's recommended in the guide. I have installed multibeast and checked all required settings including nVidia Web Driver and installed the latest Web Drivers. When booting through the USB with the 1070 plugged in the machine will not boot.

I chose the UEFI bootloader in multibeast and the partition was made bootable, however when booted to days that no OS could be found.

Sorry if this isn't enough info, or if this is a simple fix, it's my first build and nothing I tried on forums or from similar builds has seemed to work.

Motherboard: ASUS Maximus Hero VII

CPU: Intel i5 4690k

GPU: Gigabyte G1 Gaming GTX 1070

RAM: 4x8GB GSKILL Sniper Series 2133mHz
