Boot Fail on Asus 62 Chromebox

“Booting from 'USB: PNY Tech… USB 2.0FD Failed: verify it contains a 64-bit UEFI OS”

It does, where do I go from here? I am not a heavy user but was able to download your firmware and got thru your guide all the way to selecting the USB drive selection for booting to OS.

Seems I am close but not quite there.

what’s on the USB? how did you write it?

The error is pretty straightforward - your USB isn’t bootable
