Re: Trouble making bootable USB from ISO image

That is absolutely not true. Partition data, UEFI or not, bootable or
not, are just octets on a medium. They could be created with an Atari if
Atari had USB plugs, that would not make any difference.

The vague truth behind your statement is:

To edit UEFI variables, the computer need to have booted in UEFI mode.

The UEFI variables, the contents of the computer's non-volatile internal
memory. Not the contents of the drive. They contain, amongst other
things, the default boot options. They are not used when selecting the
boot option manually.
