Ok, I succeeded with the configfile approach. However I have to run 
nixos-install twice in order to eventually get a grub.cfg. I have in 
/etc/nixos/configuration.nix:

   boot.loader = {
     grub.enable = true;
     grub.version = 2;
     grub.device = "nodev";
   };

Now I can successfully boot NixOS!
