FlashBoot can install UEFI shell to the USB thumbdrive.
Using UEFI shell, you can configure boot menu items for your UEFI-compliant motherboard or notebook, load/unload UEFI drivers, execute other UEFI applications, nsh scripts, etc.
You can use this option to quickly test FlashBoot compatibility with your computer without supplying external data (OS installation CD, ISO image file etc). This option requires UEFI-capable computer to boot. Most computers manufactured after 2012 are UEFI-compatible
