How to dual boot Windows 10 from different disk?

Help

my configuration looks like this. I just let OSProber find it for me.
The manual way lets you rebuild NixOS more quickly, but if you run into issues (as I did) you can just fall back to this lazy solution :slight_smile:

boot.loader = {
    systemd-boot.enable = true;
    efi.canTouchEfiVariables = true;
    grub = {
      enable = true;
      devices = [ "nodev" ];
      efiSupport = true;
      useOSProber = true;
    };
  };
