@Fehlix,
For NUC8i5, all Ubuntu(s) I've tried (Ubuntu 18.04 & above, Kubuntu, etc, etc) boot using their ISO
dd-ed to a USB. LinuxMint too. Also Fedora. All install quickly and with no problems I've encountered.
But, using the MX-18_x64.iso
dd-ed to the exact same USB stick used for the above, it will not boot (or be recognized) by the NUC. Just dead black screen & nothing happens, no recognition by the NUC that something is on the USB stick.
echo $grub_cpu = i386.
What are the MX-Linux team's environment space (variables) when a user is booting an MX-18 Continuum ISO to install it to an either UEFI-based and/or legacy-bios machine?
It sure would be great to be able to do a fresh, clean install of MX-18 Cont. to a partition on the NVME drive in this NUC. The NVME is blindingly fast. I was able to get a fudged (frugal-like) version of MX-18 running by manually doing some things to a full-installed MX-18 on a SSD (from another machine, and plugged into the NUC via USB 3.0) and then afterwards copying stuff over, but there are (obviously) problems with this.
Anyway, hope things get sorted. Presently trying to get a few of my Pups I Woof-CE built to run on this NUC frugally
