Ah, but the system where this is happening has a strange boot
configuration (as I *think* I originally explained).  The main drive
is an NVME SSD but, being a fairly old system, this drive isn't
recognised by the BIOS.  Thus there is a small SATA SSD partition
(which *is* recognised by the BIOS) mounted as /boot.

See above!  It has *never* been recognised by the BIOS.

I haven't exhausted any ideas really, I'm just exploring what may be
wrong.

I would normally have kept the Windows partition, it was just an error
on my part that destroyed it many moons ago.
