2. I note when booted to the 15.2-1 installation that works that the mounted /boot/efi folder contains subfolders /EFI/boot and EFI/opensuse, each with files within. In each of the inactive 15.2-2 and TW root folders, however, there's nothing at all below /boot/efi. Is this
Do you know what "mount point", "mounted file system" in Linux/Unix is?

I thought I did.
The thing is that in /boot in my running system I can see a handful of (config) files and two subdirectories, /efi and /grub2. /grub2 contains a few folders and a couple of files. /efi contains another folder named /EFI which itself contains two more folders, /boot and /opensuse.
Mounting the root folder of one of the problematic installations from the working installation, I can see under /boot much the same as above - /grub2 and /efi together with a number of config and vmlinuz files, and I can enter the two folders so so I assume the parent is mounted. The /grub2 folder looks much like on the running system as above. But the /efi sub-folder contains nothing. If that means it's not mounted when its parent and companion are, then I have indeed learned something.
[] -- mount This is the structure I told you to mount (make sure your mail program displays in fixed width font): [root] |--[/boot/efi] | \----/opensuse | |--[/home] | +--[/mnt] | |\ | | -[other root] | | |\ | | | \-"/boot" | | | \___[another EFI] (*) | | | | | \--[another /home] | | | \--[ 3rd root]] (*) If that "other efi" is not mounted, it will show empty. If it is "another" EFI is mounted, it may have something, or not, depending if it is properly installed or not. If that "another EFI" has mounted the first same EFI as the first system, it will show the same directory "opensuse" as the first one, which you can verify by writing a new file in one and seeing it in two (and three) For the repair procedure I described it is crucial you have it all properly mounted as described above. This procedure is the same for any "rescue operation". -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
