Introduction

This is a complete guide on installing NixOs, using flakes.

Be sure to have an ISO image of NixOS, which can be obtained here: https://nixos.org/download/#nixos-iso.

Installation guide

Partitioning your disk

Open a terminal.
Wipe your disk: $ blkdiscard /dev/<installation disk>.
Create root and boot partitions:

Use parted

$ parted <installation disk>
(parted) mklabel gpt

Boot partition

(parted) mkpart
(parted) Partitoin name? boot
(parted) File system type? fat32
(parted) Start? 0%
(parted) End? 2GB
(parted) set 1 esp on
(parted) set 1 boot on

Root partition

(parted) mkpart
(parted) Partitoin name? root
(parted) File system type? btrfs
(parted) Start? 2GB
(parted) End? 100%
(parted) quit

Configure and mount partitions

$ mkfs.btrfs /dev/<root partition>
$ mkfs.vfat -F32 /dev/<boot partition>
$ mount /dev/<root partition> /mnt
$ mkdir /mnt/boot
$ mount /dev/<boot partition> /mnt/boot

Generate and edit config

$ sudo nixos-generate-config --root /mnt
$ nvim /mnt/etc/nixos/configuration.nix
$ nvim /mnt/etc/nixos/hardware-configuration.nix
Remember to add the following configuration so that grub works with EFI:

boot.loader.grub.enable = true;
boot.loader.grub.efiSupport = true;
boot.loader.grub.device = "nodev";
boot.loader.efi.canTouchEfiVariables = true;

Install

$ sudo nixos-install
Set root password when prompted to do so.
Reboot your machine
Login as root and set a password for your user: $ passwd <username>
Logout and login as your user
