[Nix-dev] Can't install NixOS on an NVME drive

[Julien Tanguy]

Hello Liam,

For NixOS to work, you have to change the SSD controller from RAID ON to
AHCI. This effectively *breaks *the windows install. As of today I haven't
found a better way to switch to windows than to change this SSD setting
each time I want to boot to another OS.

I wrote something about my NixOS install for a Dell XPS 15, you can read
about it here https://jtanguy.cleverapps.io/installing-nixos-on-a-xps-9560/
Domen Kožar pointed me out on Twitter to another config, with a more
elaborate setup with LUKS and such :

I hope you find what you need.
Julien
