== Why? ==

For 'normal' NixOS installations, you'd use the [instructions from ~~the manual](~~https://nixos.org/manual/nixos/stable/index.html#sec-installation).

For 'normal' NixOS installations, you'd use the instructions from https://nixos.org/manual/nixos/stable/index.html#sec-installation

However, you can install 'directly from Linux' if:

* You're feeling adventurous

* You already have a running linux distro

* You already have a running linux ~~with GRUB on your primary partition~~

* You don't want to waste a CD-R (and can't boot from USB)

* You have a spare partition where to install NixOS ready.

~~This~~ is ~~fairly esoteric, most users would use~~ the ~~[official instructions](~~https://nixos.org/manual/nixos/stable/~~index.html~~#sec-~~installation)~~

One method is described in the manual at https://nixos.org/manual/nixos/stable/#sec-installing-from-other-distro. For an alternative method, see below.

Thats it. Now follow the manual (Alt-F8), mount /dev/sda3 as /mnt, do

nixos-option and so on.
