Failed to install bootloader

Hi there @Mickhat ! From what I see in the error, it seems that it is not detecting the boot partition, so you probably need to mount this partition so NixOS can install the bootloader. Once that partition is mounted on /boot, you should have no more problems installing NixOS.

In theory i run NixOS already as a second boot, but i still get the same error, even in a VM.

The error has to do with the partitions of your computer. When installing the flake, did you replace the hardware-configuration.nix file of your system in the flake? This is important, because that file maps your system's mounts, which is different from the one uploaded in the repository. Try following the README installation instructions from bullet 2, and see if you can get it to run correctly.
