       error: The option `system.build.installBootLoader' is defined multiple times while it's expected to be unique.
       Only one bootloader can be enabled at a time. This requirement has not
       been checked until NixOS 22.05. Earlier versions defaulted to the last
       definition. Change your configuration to enable only one bootloader.

       Definition values:
       - In `/nix/store/9figz32vbiblaw5x3li1hc8q9qwlwf27-source/nixos/modules/system/boot/loader/generic-extlinux-compatible': <derivation install-extlinux-conf.sh>
