UEFI grub devices wrong

[Felix Miata]

I've replaced a failed nvme stick by restoring from backup. I get only a grub
rescue> prompt:

grub rescue> set
cmdpath=(hd1,gpt1)/EFI/OPENSUSETW
prefix=(hd1,gpt7)/boot/grub2
root=hd1,gpt7
grub rescue>ls
(hd0) (hd1) (hd1,gpt16) (hd1,gpt15) (hd1,gpt14) (hd1,gpt13) (hd1,gpt12) 
(hd1,gpt11) (hd1,gpt10) (hd1,gpt9) (hd1,gpt8) (hd1,gpt7) (hd1,gpt6) (hd1,gpt5) 
(hd1,gpt4) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1)
grub rescue> insmod normal
error: symbol `grub_file_filters' not found.

This is with only one storage device in the PC, empty DVD drive, no USB sticks
inserted, only the M.2 NVME stick. Why does it report (hd1) at all, much less
having all the partitions? On the partitions, everything is configured for hd0
being the only storage device.

This is openSUSE Tumbleweed's grub, but I'm not sure how old, so don't know
whether it's 2.02 or 2.04. When the original stick was created, the ESP had
been setup while 2.02 was installed. Since then, Tumbleweed has moved from
2.02 to 2.04.

Is it a BIOS failure? Software failure? Installation failure? What should I do?

# efibootmgr -v

PciRoot(0x0)/Pci(0x17,0x0)/Sata(3,65535,0)/CDROM(1,0x4e8dd,0x7800)..BO

BIOS seems to match this well enough.
