Pascal,you understood correctly: the GRUB is not even shown. Indeed it would be a problen, but now is secondary.If the GRUB could continue the process (after the timeout), even showing nothing, that could be temporary acceptable. The problem is that it looks like that GRUB stuck the PC.I'm convincing that the problem is the GRUB. I tried to boot from a Super Grub 2, but it stucks as well.I'm going to work with the GRUB_TERMINAL=console setting.ThanksF.--2016-02-06 0:23 GMT+01:00 Pascal Hambourg <pascal@plouf.fr.eu.org>:Brian a écrit :

IIUC, the GRUB menu is not even displayed.
However you may be correct about a graphics mode issue, but in GRUB, not
the kernel. I have seen it on a couple of machines/graphic cards.
Boot the system on the other machine or chroot from the installer or any
live system.
Edit /etc/default/grub to uncomment GRUB_TERMINAL=console.
Run update-grub to regenerate the grub config file.
Try to boot again on the single board.
