Guix installation image

[Alexander Asteroth]

Dear all,

I would really like to install Guix on my Dell XPS 13 (9380) and give Guix a
try not only in VM bur on a my main device. Unfotunately it refuses to
boot the installation image. After selecting the boot device I only see
a nonbliking cursor.

I checked the partition table of the image and was supprised so see:

> sudo fdisk -l /dev/sda
> GPT PMBR size mismatch (2694403 != 4014079) will be corrected by write.
> The backup GPT table is not on the end of the device. This problem will be 
> corrected by write.

is this really how it's supposed to look like?
