!!!THIS SCRIPT WILL ERASE YOUR ENTIRE DISK = ALL DATA WILL BE LOST!!!
Use at your own risk, ideally on a new computer. NEVER use it on existing installations as this installer will overwrite your disk.
Download the latest graphical live NixOS from https://channels.nixos.org/nixos-22.05/latest-nixos-gnome-x86_64-linux.iso and create a live USB (replace VERSION.COMMIT and sdX with appropriate values), e.g. (be careful):
$ sudo dd if=Downloads/nixos-gnome-22.05.VERSION.COMMIT-x86_64-linux.iso of=/dev/sdX bs=1M && sync
Make sure SATA mode is set to AHCI, i.e. disable Intel Rapid Storage Technology, if it's present.
Boot into live disk and start and connect to the Internet.
Open Terminal and download the installation script:
$ curl -O https://raw.githubusercontent.com/1000101/ni/master/ni.sh
Run the installation script:
$ sudo bash ni.sh
The script will guide you through the installation process.
Don't forget to write down the password (same for root&encryption).
Login as root and set user password:
# passwd yourusernamehere
Then logout and login as user.
Enjoy!
