The latest stable release series is 14.04. Below are links to CD/DVD images and VirtualBox appliances containing the latest release in this series.

Installation CDs/DVDs

You can install NixOS on physical hardware by burning one of the CD images onto a blank CD/DVD disk, or by copying it onto a USB stick. For installation instructions, please see the manual.

Please note that NixOS at the moment lacks a nice, user-friendly graphical installer. Therefore this form of installation may not be suitable for novice Linux users.

The graphical installation CD contains the NixOS installer as well as X11, KDE 4 and several applications. It’s a live CD, so it allows you to get an impression of NixOS (and the Nix package manager) before installing it.

The minimal installation CD does not contain X11, and is therefore a lot smaller. You have to run the installer from the console. It contains a number of rescue tools.

VirtualBox appliances

This is a demo appliance for VirtualBox (in OVA format) that has X11 and KDE enabled, as well as the VirtualBox guest additions. To use it, download the OVA file, open VirtualBox, run “File → Import Appliance” from the menu, select the OVA file, and click “Import”. You can then start the virtual machine. When the KDE login screen appears, you can log in as user demo, password demo. To obtain a root shell, run sudo -i in the KDE terminal (konsole).
