Two EFI volumes in external Bootcamp restore

I successfully restored a Bootcamp image onto an external USB 3 SSD. The image was taken from a Mac Mini (2014). I’m using a 2017 Macbook Pro to run it. I have two issues so far:

  1. When I restart while holding option, I see two orange EFI volumes, instead of a Bootcamp volume.

  2. I’m able to boot from one of the EFI volumes, but I have no use of Macbook Pro keyboard or mouse once I get to the Windows login screen.

Based on another question on these forums, it sounds like issue 2 might be addressed by reinstalling bootcamp drivers via VMWare Fusion? If so, please explain which drivers to install.

I have no idea what’s going on with issue 1. Why don’t I see a single Bootcamp partition with the Bootcamp icon?
