How to launch EFI Shell from filesystem drive?

[LukeZhang]

Hi I have zenbook 14x oled and the bios has `Launch EFI Shell from filesystem drive` menu.
But I am newbie and has no idea how to jump to efi shell using this feature.

When I am clicking this, it shows error popup with `Not Found`.

Any idea?

The EFI Shell itself is a system and requires you to find and install it on your own.
Thank you.
