I've probably parsed dozens of pages now, including the "Dual boot NixOS and Windows" page on nixos.wiki, and not really sure what the best steps are since most seem to leverage the fact that everything is on a single partition. My windows lives on a physically separate drive than NixOS, so osprober does not detect the windows partition at all. I tried to go down the route of grub-mkconfig but that doesn't seem to be a nix package and I couldn't mount my Windows bootloader as it is NTFS. Is this even possible with this configuration?

My next step was going to be to physically disconnect each of my disks/NVME, nuke everything bit by bit, then only connect the disks I want and install each OS with it's specific disk connected.

I see you can delete everything older than some period of time, but what if I want some older than a year? Or should it be interpreted that: whatever build configuration was used, it is tested thoroughly at that point, and it would be better to rebuild from a nix configuration stored on git?

Edit: my issues came from copying source .nix configurations for the pig manager, not configurations that I would include on my computer. Finding how to include what where was much easier with search.nixos.org

Hi, I've finally cleansed my system of windows and switched fully into nix. I want to learn this OS the right way, but have ran into some noob troubles. Any help would be greatly appreciated. Ideally, these changes are things I would include in my configuration.nix

• How to install electrum wallet on nixos? I found this default.nix for electrum and thought it would be as easy as nix-build default.nix but was mistaken. It says " cannot evaluate a function that has an argument without a value ('fetchurl') Nix attempted to evaluate a function as a top level expression" but on a later line that value is inputted to the function (if I understand right)

src = fetchurl { url = "https://download.electrum.org/${version}/Electrum-${version}.tar.gz"; sha256 = "sha256-BxxC1xVKToUjgBo4mEeK9Tdhbd/+doHcTTJsXDtaELg="; };

• How to install KVantum Theme Manager? I was following this guide and tried to add gcc/g++ and the x11 package dependencies but I get undefined variables for the x11 libraries. Some recommend using stdenv.mkDerivations but I haven't used that much nix before so I'm not certain if I should be going down that rabbit hole

I'm conflicted on what should handle my login manager, desktop environment, and window manager. What are the pros and cons of doing it from a nixos configurations versus a home manager configuration?

I want to use Plasma-manager in my system. I have enabled flakes in configurations. Now what to do to use it.
