Sorry the installation failed for you :(.

While it's true that the Guix installer doesn't reformat the ESP
partition if it already exists, that shouldn't cause any issue. That's
what happened when I installed Guix on my X1 Nano.

> Effects: It creates a GRUB2 error which states that it can not find

Could you share the Grub error you encountered?

Thanks,

Mathieu
