I ran into this upgrading one of my EFI machines to the latest bewolf,
it would only boot to the grub prompt.

I can't remember the exact steps I did to determine the cause, but it
ended up being that the EFI 'loader' was looking for the EFI grub.cfg in
EFI/debian, and not devuan.

My fix was to create a directory named debian under the EFI directory
and copy the files from devuan into debian. This got the system booting
normally again, I just had not had a chance to dig in any deeper and
post a possible bug report.

Anyway, as for getting the system started to even get to this point, I
suggest using this page as a reference, under the section of "Using the
GRUB2 boot prompt" (
https://docs.fedoraproject.org/en-US/quick-docs/bootloading-with-grub2/ )

Nutshell, at the grub prompt:
- ls to find the drives grub sees and find the EFI filesystem
- set root= to point grub to the root filesystem for the OS
- linux to point grub to the kernel to load
- initrd to point grub to the initrd to load
- boot to see if it all works

Hopefully this helps you get the system booting
