OK, so that's why the removable media path stuff isn't working for
you. There *was* a small window of time where the code I added in
grub-installer was doing the wrong thing with setting that variable
(#792247) which may explain this - if that's the cause of your issue,
I'm sorry. :-(

There's a simple fix for you now - "dpkg-reconfigure -plow
grub-efi-amd64" and set that variable to true. It should now work as
needed.
