I want an image of the NVME drive I can use on any disk to create a working drive. I tried the Disks app, and discovered it doesn't compress the image, and since the image created is a bit over 500 Gb, I can only write it to a drive larger than 500Gb. (sigh) I think the problem is that the NVME drive is actually a fraction over 500Gb, since if I try to clone it to a 500Gb drive I get a message that the receptor drive is too small. I was told I can reduce the partition on the NVME drive to make a smaller image, but I'm afraid to do that in case I lose data. I will try Rescuezilla, but if that doesn't compress the image there's no gain from that. Does anyone have any better suggestions for what I can do? thanks to all. :)

For this setup, I did the following.

1) Install LM223 UEFI/GPT on NVMe (512GB)
   Custom install: ESP first, BIOS-GRUB second (10MB, maybe only needs 1MB?), EXT4 slash, small swap
   As near as I can tell, the BIOS-GRUB was not populated by GRUB during install.
   As it is a NoFS partition, I like to keep those towards the left if possible.
   (Like, to the left of Microsoft Reserved, which is another NoFS partition, on dual boots.)
   The BIOS-GRUB partition is my "escape clause" :-)

2) Backup with Rescuezilla to 256GB scratch.

3) Restore to 1TB HDD. Put the drive into Legacy-only machine (Optiplex 780 E8400 Core2Duo)

4) Didn't boot. Blinking underline-cursor.

5) Tried Boot Repair DVD. Didn't work. Whined about either booting as UEFI (cannot do
   on Legacy computer) or it was complaining it did not have the BIOS-GRUB files like the
   LM223 DVD should have. At this point, I added a second EXT4 for a second OS install.
   I installed LM223 from the DVD, and the DVD would boot in Legacy Mode.
   There was some GRUB activity, so it did seem to try installing (in more than one place).

6) This time, my pair of OSes are now booting in the Legacy Machine, using their newly installed GRUB.

So my "extra partition" did the trick, by providing a storage place
for the GRUB .img file. There is still No_FS in the BIOS-GRUB partition,
it is a .img file "dd" transferred into the start of the partition. That's
what the label in GParted shows.

Summary: You can get there. It's the usual amount of annoyance.

And the Image-Explorer in RescueZilla works. I did a fresh boot of the
RescueZilla USB stick (Rufus) and if you do Image-Explorer first thing,
it seems to work. The PartClone (...ptcl) should not be compressed if you plan
on doing that.
