Beginner here. I was trying to add a configuration to the Grub 2 bootloader, but running
sudo nixos-rebuild boot
is just not going forward.
Currently on NixOS Ver 24.05 dual booted on the same disk with Linux Mint (where Mint was downloaded first). There are four total partitions, with Mint on sda3 and Nix on sda4.
The following are the logs after running the command. Help is always appreciated.
building Nix...
building the system configuration...
updating GRUB 2 menu...
Warning: os-prober will be executed to detect other bootable partitions.
Its output will be used to detect bootable binaries on them and create new boot entries.
