I friend

Are you saying that the upgrade of the guix did broke the boot system? But
they show not message. How do I reinstall the boot using the pendrive of
Guix System Installation? Can I boot from pendrive then install the grub? I
think I need to think like a Guix user because guix deamon control many
think.

I need to warning the GNU community that the grup.pdf has no instruction
about how to boot a HDD from a pendrive manually.

The Trisquel and Guix System pendrive show not option to HDD boot. I think
this option exist with a normal situation.

Thanks for the feedback.
