Yes, the error I'm getting is "grub-install dummy failed," and at the exact point which you described.
I was looking at some potential solutions, like the one at https://wiki.debian.org/GrubEFIReinstall
but when I got to step 2 there were some immediate problems:
I tried passiing the kernel parameter "efi=runtime" by pressing the 'e' key with Graphical Rescue selected, then adding that parameter to the line beginning with 'linux.' I then booted (Ctrl-X) into rescue mode, but the directory /sys/firmware/efi/efivars remains empty, and any attempt to mount it results in failure, just as it did when automatically selecting the default rescue mode parameters.
I'm very interested in learning your method of getting Debain to boot off the microSD.

My partitioni scheme is heavily cutomized but I don't think it'll be an issue in this case, as all directories mentioned in the tutorial are contained on the root (/) parititon (/, swap, /home, /srv, /tmp and /var are their own separate primary partitions). There is also an EFI partition that I created first during setup.
I'm definitely willing to give your way a try with this setup.
Thanks again for your detailed instructions. esterday I didn't even think I'd get this far.
