Quick Start

Method 1: Fresh NixOS Install (Two-Phase)

Phase 1: Install Base NixOS

Boot NixOS ISO
Partition and format disk:

# For BIOS/Legacy (like Proxmox with legacy BIOS)
parted /dev/sda -- mklabel gpt
parted /dev/sda -- mkpart primary 1MiB 2MiB
parted /dev/sda -- set 1 bios_grub on
parted /dev/sda -- mkpart primary 2MiB 512MiB
parted /dev/sda -- mkpart primary 512MiB 100%

mkfs.fat -F 32 -n boot /dev/sda2
mkfs.ext4 -L nixos /dev/sda3

mount /dev/disk/by-label/nixos /mnt
mkdir -p /mnt/boot
mount /dev/disk/by-label/boot /mnt/boot

Generate and edit config:

nixos-generate-config --root /mnt
nano /mnt/etc/nixos/configuration.nix
# Add bootloader config (see configuration.nix for example)

Install and reboot:

nixos-install
reboot

Phase 2: Apply Custom Configuration

# After rebooting into fresh NixOS
nix-shell -p git
git clone https://git.cribdev.com/crib/nixos-config.git ~/.config/nixos
sudo cp /etc/nixos/hardware-configuration.nix ~/.config/nixos/

cd ~/.config/nixos
# Edit hostname in flake.nix and configuration.nix
# Edit username and other settings

sudo nixos-rebuild switch --flake .#YOUR-HOSTNAME
reboot

Method 2: Direct Install with Flake (Advanced)

From the ISO after partitioning:

nix-shell -p git
git clone https://git.cribdev.com/crib/nixos-config.git /mnt/etc/nixos
nixos-generate-config --root /mnt --show-hardware-config > /mnt/etc/nixos/hardware-configuration.nix

# Edit configs
nano /mnt/etc/nixos/flake.nix
nano /mnt/etc/nixos/configuration.nix

# Install with flake
nixos-install --flake /mnt/etc/nixos#YOUR-HOSTNAME
reboot

Configuration Checklist

Before first build:

Edit flake.nix: Change hostname from "myhost"
Edit configuration.nix:
- Set hostname
- Choose bootloader (GRUB for BIOS or systemd-boot for UEFI)
- Set timezone
- Update username from "crib" if needed
Edit home/home.nix:
- Confirm username is correct
- Set git name and email
- Customize package list

Bootloader Configuration

For UEFI Systems:

boot.loader.systemd-boot.enable = true;
boot.loader.efi.canTouchEfiVariables = true;

For BIOS/Legacy Systems (Proxmox default):

boot.loader.grub.enable = true;
boot.loader.grub.device = "/dev/sda";

Important: Make sure your partitioning matches your bootloader choice!

Hyprland Keybindings

Default modifier key: SUPER (Windows key)

Basic

SUPER + Return - Terminal (Kitty)
SUPER + D - App launcher (Wofi)
SUPER + Q - Close window
SUPER + E - File manager
SUPER + V - Toggle floating
SUPER + F - Fullscreen

Workspaces

SUPER + 1-9 - Switch workspace
SUPER + SHIFT + 1-9 - Move window to workspace

Screenshots

SUPER + SHIFT + S - Screenshot to clipboard
Print - Screenshot to ~/Pictures

Updating the System

# Update flake inputs
nix flake update

# Rebuild
sudo nixos-rebuild switch --flake ~/.config/nixos#YOUR-HOSTNAME

# Or use alias (after first build)
update

Troubleshooting

Build Errors

"undefined variable 'X'"

Package name has changed in newer NixOS
Check this fixed config for correct names

"wrong type for EFI System Partition"

Bootloader mismatch - check your partitioning and bootloader config

"file exists" errors

Likely duplicate configuration
Check for conflicting options in different files

Performance

Slow first build?

Use Hyprland cachix: nix-shell -p cachix --run "cachix use hyprland"
Allocate more RAM/CPU to VM if using Proxmox

Key Differences from Original Config

This version is specifically updated for:

NixOS 25.05 and newer
Proxmox VMs with legacy BIOS
Latest package names and APIs
Removed all deprecated options
