Nixos installation with lustrate or iso

Hey everyone,

I’ve been struggling to install nixos the past few days.

First the iso (all the available isos in nix site) won’t work for me, I get errors when trying to mount /dev/root.

Then I tried installing in place using manual: installing from other distro. Everything worked okay but the last step, in which I need to backup boot and run sudo /nix/var/nix/profiles/system/bin/switch-to-configuration boot

This failed saying doesn’t look like efi partition, First I thought maybe I need to change something in my configuration.nix and set the value of boot to boot/efi. Nope same error:

sudo /nix/var/nix/profiles/system/bin/switch-to-configuration boot

	LC_TIME = "cs_CZ.UTF-8",
	LC_NUMERIC = "cs_CZ.UTF-8",
	LANG = "en_US.UTF-8"
    are supported and installed on your system.

Now what I’m doing wrong and did I miss read the manual in some way?
