Hi there,

AFAIK there's no stable branch of Guix.

Please share the code of your Guix system configuration and the exact
error message you received.

I'd normally expect efibootmgr errors when trying to install a UEFI
variant of GRUB while being booted in legacy mode. So you can first
make sure your USB is booted in UEFI mode before trying to install a
UEFI GRUB. Alternatively, you can install the OS in legacy mode (i.e.
without using ESP) and then set your laptop to boot from disk in legacy
mode. Please look into Guix documentation to find information on how to
perform both types of installation

Best,
wojtek

I was able to successfully install it on my laptop, but when I ran "guix pull" and "guix system reconfigure", the updating process failed to install the bootloader on my ESP partition. As a result, when I rebooted my laptop, I couldn't boot normally to my GNU Guix System and no GRUB bootloader was found.

I received a message about efibootmgr. Eventually, I switched to the installation of my NixOS Linux and successfully installed it on my HP laptop from which I am reporting this issue to the Guix community.
