NO USB BOOT OPTION in BIOS

I am trying to install a clean form of Windows 10 via USB but I can not get the USB option to boot from. I have tried different formats and finally I got Microsoft to do it for me but Still in my bios I cannot boot from either Legacy nor UEFI. I even tried making it optional by typing in USB ODD and then efi\boot\bootx64.efi and it still will not boot from my USB.

My USB is 8GB just under it.

here are my specs.
