I have a plan but I need some more information. Is there any personalization done by the boot setup process? Do our UUID's or any other specific information pertaining to the installation make it in to the initrd files? While reading about the boot process, it doesn't appear that the initrd files or initranfs are personalized with anything pertaining to this computer and this installation. If that is so, then two computers using the same processor type should be able to use copies of the same initrd files and the only thing that is personalized on an individual computer is all the grub configuration in which the UUID's of at least / and /swap partitions are sprinkled throughout grub.cfg and /etc/default/grub. One should be able to write a program to get the appropriate UUID's out of fstab on the working system and translate them in to corresponding UUID's for the system on the operating table. If the target system actually boots, it is probably a good idea to run update-grub to make sure that still produces a working boot but this would still more than likely produce the same results if this process works in the first place. It's also possible that the reconstructed grub setup is okay except for the drive designation which usually starts out as /dev/sda1. On my good Buster system, this is now /dev/sdc1 and on the sick one, the attempt is being made on /dev/sda1. The idea here is to copy the concept of what is happening rather than the literal configurations which definitely will never work unless one used dd to generate the clone drive and I have actually done that once and it worked but the cloned system was then adapted for other uses. Here, all I want to do is rescue the boot process so it lives on and not have to reinstall everything else. As an aside, one ought to be able to do something like this. It makes life a lot simpler. Both systems are using the same kernel and versions of the same processor the only real differences are the UUID's. The grub configurations of both are the same down to the serial console. Martin
