You and Peter may be desensitized to shitty computer behavior, and specs. But consider that Kamil's sequence would not have failed to boot on legacy BIOS+MBR hardware either.

I find it surprising that a 2200 page spec, and the efforts of the UEFI Forum result in such spectacular failure, in a common and unremarkable situation. It seems exceptionally regressive.

Curious, how are manufacturer's using bulk imaged disks, separate from the computers they will be installed in, and yet the computers still manage to UEFI boot? I can't believe manufacturers would give up bulk imaging capability, or have someone type commands into each machine's NVRAM.
