Prepare a NixOS installation media and boot into it.
Open the terminal and run the following commands. Read thoroughly before running each command.
# Fetch NixDots and `cd` into it
nix-shell -p git --run "git clone https://github.com/Voxi0/NixDots.git"
cd NixDots
# Set your username (Set to my personal username by default `voxi0`) and the disk where NixOS is installed (REQUIRED)
nano ./flake.nix # Nano is installed by default, use another editor if you want
# List all mounted disks to choose a disk to install NixOS on
lsblk
# Run the install script
# Replace `<install_disk>` with the name of the disk to install NixOS to e.g. `/dev/sda`
# Replace `<hostname>` with the NixDots host to install/build e.g. `neo`
./install.sh <install_disk> <hostname>
# Chroot into the new system to run additional commands like changing your password
sudo nixos-enter
passwd root # Change the root password from `nixos` to something else if you want
passwd <your_username> # Definitely change your password from `nixos` to something else
# Installation is complete! Power off and remove the installation media
