Yes, it did help ! In fact I was able to start the process

BUT

it didn' t end correctly :-/

Installing for i386-pc platform
grub-install: error: cannot find a GRUB drive for /dev/sd1. Check your
device.map.
guix-system: failed to install GRUB on device '/dev/sd1'


As far as I understand my platform should be x86_64
Why did it select i386 ?

Also: what did I mess up with grub ?

/dev/sda1 is a small partiton mapped to /boot

Is that wrong ? Does grub require to be on '/' ?
