I would really like to try out GuixSD using Windows 10 host. I am following
the instructions
https://www.gnu.org/software/guix/manual/en/html_node/Installing-GuixSD-in-a-VM.html

The first question is about the point " In the VM console, quickly press
the F12 key to enter the boot menu. Then press the 2 key and the RET key to
validate your selection."

F12 key does absolutely nothing, however Esc shows the boot medium
selection - is this what F12 is supposed to do? Is there an error in the
instructions or is the QEMU on Windows is just different?

If I select the 2 (guixsd.img) booting fails. Again, error in the
instructions?

Selecting 1 (guixsd-install-0.16.0.x86_64-linux.iso) boots and I should
create partition on the guixsd.img that is /dev/sdb, right? (And after that
mount it on /mnt, etc...)
That fails saying "floppy: error 10 while reading block 0".

Help would be helpfull  : )
I am pretty much stuck now.
