Hi, I've followed instructions on this page: https://www.gnu.org/software/guix/manual/html_node/USB-Stick-Installation.html#USB-Stick-Installation
everything goes smoothly and at the end I get a partition named "gnu-disk-image" with flag "boot". Sounds good. When I mount it it's a classical GNU / Linux root with folders bin, root, dev, etc, gnu, home, mnt, root, run, tmp and var. However when I reboot the key isn't recognised by my laptop so I'm unable to install it :'( Any ideas how I could solve that? Thanks in advance, piotr
