I swapped off an existing swap partition in the target drive (but not the zram), and tried like in the previous comments (# 20-21).
The error [message] was exactly the same, so we should *not* blame the DVD drive or some unique hardware component or unique UEFI-BIOS system.
@Simon,
Something goes wrong when trying to install the bootloader in UEFI mode and it does not find a file. Have you tried according to the 'built-in tip' to specify --target or --directory?
I tested in the Intel NUC, described in the duplicate bug report
