Installation Error

Hello, I have a Dell Inspiron 3521 and I’ve been trying install nixos and I used Etcher to create a bootable USB but I’m unable to get it running. When I try to boot in to the system it says “You must set the option 'boot.loader.grub.devices” and display errors. I’m trying to install the Graphical ISO image. Please help.

I don’t understand what you have done here.

To make the USB flash drive to boot off of, you should probably follow the instructions here: https://nixos.wiki/wiki/NixOS_Installation_Guide#Making_the_installation_media

Then proceed to https://nixos.org/manual/nixos/stable/index.html#sec-installation

Are you getting the error after booting from the USB flash drive, or after installation and trying to boot from the disk in the Dell machine?
