I see nobody has replied.

We discussed this at the Humbug meeting, and none of us had much of a
clue most because none of us have used systemd-boot.  I gather it's a
signed EFI shim that does boot loading.  Also, it sounds like you are
booting Windows from something other than SATA-O (ie, not the C drive).
That has caused some of us a world of pain in the past.  There were some
claims that grub had magic to handle that - somehow hiding the other
drives so it looked to Windows as it if was booting from C.

So you have combined using systemd-boot and trying to run Windows from
something other than C, and it all gets too hard.  There were only two
suggestions - bring it into the next Humbug meeting so we can all have a
poke at it, or re-arrange your drives so Windows boot's from C.  Linux
can boot from anything after all ...
