Thanks, Mark.

I have tried the following:

1. check the guixSD DVD with a laptop without libreboot. It boots without problem. ==> The DVD disc is ok.
2. check the guixSD DVD with the laptop with libreboot. It will not boot for
   nither *Search ISOLINUX menu (CD/DVD) (d)
   or *Search for GRUB2 configuration on external media
3. check the DVD drive of the laptop with librebook using another DVD with Trisquel GNU/Linux image. It boots without problem. ==> The DVD drive is ok.

There must be something incompatible for both guixSD image and libreboot.

Hope this helps for further analysis.

best regards,
wxie

Instead of "Search ISOLINUX menu", could you try using "Search for GRUB2
configuration on external media"?  This is the method I've used in the
past on my Libreboot X60 and Libreboot X200 machines.

The last time I researched it, I learned that booting from USB in
Libreboot was somewhat unreliable, at least in some configurations.  It
might depend on which USB port you use, so please try different USB
ports.  It might depend on the USB stick, so maybe try another stick.
It might also be important to have the USB stick plugged in before you
power up the machine.  Finally, it might be a matter of chance, so you
might need to try it several times before it works.

Please let us know how it goes.
