Yes, it is now booting.  This is with the rEFInd stick:
root@mc:/boot/efi/EFI# mount /dev/sdf1 /boot/efi
mount: /dev/sdf1 is already mounted or /boot/efi busy
       /dev/sdf1 is already mounted on /boot/efi
root@mc:/boot/efi/EFI# apt-get install --reinstall grub-efi

A baffling point:  In rEFInd the path is /boot/efi/EFI/debian/grubx64.efi

After booting up into the HDD instance, I get:

root@RoxTor:/boot# ls -a
.   config-4.0.0-2-amd64  grub                System.map-4.0.0-2-amd64
..  efi              initrd.img-4.0.0-2-amd64  vmlinuz-4.0.0-2-amd64
root@RoxTor:/boot# cd grub
root@RoxTor:/boot/grub# ls -a
.  ..  fonts  grub.cfg    grubenv  locale  unicode.pf2  x86_64-efi
root@RoxTor:~# cd /boot
root@RoxTor:/boot# cd efi
root@RoxTor:/boot/efi# ls -a
.  ..

This is nothing past /boot/efi

Any idea what is going on?
