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

[Julien Tanguy]

I just stumbled upon this reddit post which explains how to do the trick
without reinstalling windows:
https://www.reddit.com/r/Dell/comments/66fr15/xps_15_9560_w_samsung_pm961_had_raid_not_ahci/

The trick is apparently to relax windows' safeboot rules to allow it to
boot into safe mode, then reboot to install the correct drivers.

I updated my blog post for future reference.
