The machine here is ThinkCentre 1S3237C13MJTVBGW.  Older than 
machines commonplace now.

It has UEFI but I couldn't make it boot the machine. Noticed comments 
on the Web mentioning bugs in some early EFI implementations.  So I 
kept GPT on the drive and reverted to BIOS.

Understood.  Have that.  Not using it.  Booting with BIOS rather 
than EFI.

Incidentally, the Void Linux system on (hd1,gpt6) boots when directed 
from the BIOS.  The problem is to boot it through Grub on (hd0) 
without switching in the BIOS.

If my /etc/grub.d/40_custom is problematic for update-grub2 an error 
message from update-grub2 or grub-mkconfig could help.  Don't see a 
way to get a progress or error report without recompiling.

The /boot/grub/grub.cfg created by update-grub2 is at 
https://easthope.ca/grub.cfg .  My 40_custom stanza is there but not 
in the boot menu.  If someone can spot an error, good, thanks.

Thanks,                        ... P.
