Dear guix: I have downloaded: https://alpha.gnu.org/gnu/guix/guixsd-install-0.14.0.x86_64-linux.iso.xz And follow the instruction https://www.gnu.org/software/guix/manual/html_node/USB-Stick-and-DVD-Installation.html#USB-Stick-and-DVD-Installation to make the DVD. The DVD is ok to boot from a normal laptop (without libreboot). When I insert the DVD to my laptop with libreboot, and reboot to boot configuration, and select *Search ISOLINUX menu (CD/DVD) (d) The laptop does not boot to guixSD, but stays in the boot configuration menu after reading the DVD. I have got no error message on the display. So I want you to check if there is a problem. best regards, wxie -- I'm an FSF member -- Help us support software freedom! https://my.fsf.org/join
