When I go to the BIOS tab there is no boot options priorities. I had it once but I then inserted the USB and reset and now I can only see the boot configuration, no boot option priorities. I am attempting to boot from a USB. Please help, I have a gigabyte x470 ultra gaming motherboard, EVGA GeForce GTX 1060 6GB GPU, CORSAIR CX-M Series CX550M 550W 80 PLUS BRONZE power unit, Crucial MX500 M.2 2280 500G SSD, CORSAIR Vengeance RGB Pro 16GB (2 x 8GB) I just assembled the computer I have never had an OS on it before
