After several days of frustration, I finally have mixed success... I tried a bunch of different ways to make the drive switch from Legacy boot to EUFI boot, and nothing seemed to work... I tried doing new installs from both a Live-USB stick and from an install DVD, saying to not format any directories but the /boot and /boot/efi and got failures on the installing system step ![:(]( "Sad")
I finally gave up and tried doing a fresh install of everything but /home, with the intent of then running a restore of my Timeshifft snapshots - I got a system that would boot, but then the Timeshift restore made it unbootable again ![:x]( "Mad")
It appears that it overwrote the /boot/efi and /boot directories sort of making them back into legacy boot.
So I did yet another install from scratch, except for /home, putting the /boot/efi and /boot directories on the SSD, and everything else on the NVMe drive. This boots, and I get the lsblk list that is about what I'm after, with everything except the boot files on the NVME drive....
The downside is that I had a LOT of other stuff on the system, both programs I'd added from the repository, and some that I'd had to compile from source as they either weren't in the repository at all, or only with (much) older versions.... I'd really like to do a selective restore from my Timeshift snapshots, but it seems not obvious how to do it without breaking things AGAIN... Since it is off-topic for this thread, I will be starting a new one about this.
Again, many thanks for the help you've given me!
