Install

The graphical installer is trivial. However, the minimal ISO doesn't handle partitioning for you.

Partitioning and Formatting

```bash

  1. Create a new GPT partition table

parted /dev/sda -- mklabel gpt

  1. Create the EFI Boot partition

parted /dev/sda -- mkpart ESP fat32 1MB 512MB parted /dev/sda -- set 1 esp on

  1. Create the Root partition (ext4)

parted /dev/sda -- mkpart primary ext4 512MB 100%

  1. Format partitions

mkfs.fat -F 32 -n boot /dev/sda1 mkfs.ext4 -L nixos /dev/sda2

  1. Mount the root partition

mount /dev/disk/by-label/nixos /mnt

  1. Mount the boot partition

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

  1. Create a 4GB swapfile (adjust size as needed)

dd if=/dev/zero of=/mnt/swapfile bs=1M count=4096 chmod 600 /mnt/swapfile mkswap /mnt/swapfile swapon /mnt/swapfile ```

Generate a config and install

``` nixos-generate-config --root /mnt

  1. Edit the config to your desire

nano /mnt/etc/nixos/configuration.nix

nixos-install ```
