In same boat here. I just do not understand the *EFI stuff anymore, and I've tried.
I somehow got refind to work, after disabling some vaguely named "secure boot" option in the BIOS. It shows my several linux options, and the only one that works is "rescue", that boots what is apparently a systemd bootloader with Nix generations. When I select Windows, I get some windows boot menu/loader instead of directly booting Windows.
I have no clue how it all works - there is some partition with some files, but I also must run some command to "apply" changes - I think. It's horrible.
