I speculate that identical installs are identical and the devil of the detail is in the efi partition and the boot setup. When you re-install the efi partition is NOT recreated and for me a reinstall usually fails. Being too clever for words I made a new partition, but that too failed. dd /dev/zero was my friend (in case somebody who did not get the hint reads this: dd if=/dev/zero of=/dev/sda bs=1M) whereupon all is sweet. I have managed to move a disk from 1 NUC to another and have it work. I’ve also failed doing this. I speculate that during boot the machine writes to the efi partition, that WHAT it writes allows/disallows another machine to use THIS disk.
