Actually, that's not your problem. My best guess is that you've done
an installation booted in BIOS mode, not UEFI mode. That's why you've
got grub-pc installed rather than grub-efi-amd64. Do you actually care
about booting via UEFI, or are you just looking for a bootable system?
If the latter, simply reformat your ESP (/dev/sdb1) to be a normal
ext2 or ext3 partition and use that as /boot. You could even do a RAID
/boot using sdb1 and sdc1 together...
I am sure that my "bios" is UEFI.
But I have done as you say, in case it exists an hypothetical "BIOS mode" in
UEFI :
root@nous:~# grub-install /dev/sdb1
Installing for i386-pc platform.
grub-install: warning: File system `ext2' doesn't support embedding.
grub-install: error: filesystem `btrfs' doesn't support blocklists.
And it fails (as usual with a initramfs prompt)...
Sorry, should have been clearer. Try "grub-install /dev/sdb" to
install to the MBR of the disk, not the partition.
In fact...
If you're going to try that configuration, you'll also want to
# apt install --reinstall grub-pc
with the new /boot mounted, to set everything up there too.
