I have the latest BIOS version and boot using F9 and select file as explained in first post.It is either BIOS option, old BIOS version, or incorrectly configured/created USB. Try different things. Different USB stick, different USB ports, update BIOS version if you don't have the latest, reset BIOS to defaults and revisit important options, etc.
Prior to installation, you're booting from USB using Esc+F9 to reach BIOS boot menu.
I have given the Linux comparison because I already test to boot Clover, copying the contents from first post, directly to the EFI partition on my HDD, that where it stands the files that boots Linux (replaced the BOOTX64.EFI and copied the Clover folder).
