NixOS - Installation on gtx1050 drivers

My computer faced two issues: 1) Graphic card driver incompatibilities. 2) Unable to boot from nixOS liveCD.

I referenced the following to resolve these: gtx1050 - https://github.com/NixOS/nixpkgs/issues/44284 Installation via another distro - https://nixos.org/nixos/manual/index.html#sec-installing-from-other-distro

Regarding 2) I used an ubuntu LiveCD, used nixos rather than nix when adding nix-channels
