Booting from a USB or CD/DVD drive can be tricky depending on your computer's BIOS / UEFI setup. In this guide, we'll break it down step-by-step. 'The selected File is not UEFI BIOS!!!' It sounds like you may have downloaded the wrong BIOS update -it may be a Legacy BIOS update for a different board (or an earlier revision of your board) instead of the UEFI BIOS update which your board needs.
How to Boot to UEFI Firmware Settings from inside Windows 10
UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs, designed to replace BIOS (basic input/output system). This standard was created by over 140 technology companies as part of the UEFI consortium, including Microsoft. It's designed to improve software interoperability and address limitations of BIOS.
This tutorial will show you how to boot directly to your motherboard's UEFI firmware settings from inside Windows 10.

This only applies if your PC's motherboard has a UEFI firmware chip instead of a BIOS chipset.
This only applies if Windows 10 was installed using UEFI, and not legacy BIOS (CSM).

I went into my UEFI boot menu yesterday to try to boot to a USB drive and noticed the kanji-looking characters in the screen shot provided. I couldn't use the up/down arrow keys to select a different boot device. The tab key would take me to the 'Enter Setup' and 'Boot Default' buttons and both of those did what they were supposed to do.
Setup:
This is an Asrock X99X Killer running firmware ME FW 9.1.37.1002 and the most current UEFI/BIOS version P.340.
What I've tried so far:
1) Mouse-clicking the grey 'X' above the Windows Boot Manager item, but it did nothing.
2) Re-flashing BIOS/UEFI same version.
3) Removed the only hardware item that had changed, a Corsair Strafe USB keyboard and went back to the previous one to see if the keyboard might have been the issue, but no such luck.
4) I thought there might be some drive corruption so I ran chkdisk /f on all the drives. Chkdisk didn't find anything and there was no change in the boot menu behavior.
5) I tried disabling some USB settings, but none seemed to have any affect on the boot menu.
The boot menu was working fine last week when I used it. I am able to change the boot order in full set-up mode in the UEFI, but that's a little more involved than selecting from the boot menu.
Does anyone have any ideas what else I might be able to try to get the boot menu working again?
Thanks in advance!
