Installation of Trisquel 8 looks fine each time, but after reboot, there is no way to make it boot. Impossible to make the computer to boot GRUB.

After a lot of playing in the BIOS, no workaround found. Tried: disable "Secure Boot", disable "UEFI", disable "Intel Trusted Platform", enable "Legacy support", set "boot to Legacy first".

However it is possible to boot a Linux (Linux Mint 17.3) located onto a external HDD (after enabling USB boot on power on : FN+F12).

BIOS Version (BIOS upgraded in july 2018 from Windows 10) : E5CN62WW.
