 Thanks... ill install windows to see if everything else works. Its weird that the other person that created the thread had the same problem with the exact same nuc.

You can boot memtest86+ off a USB memory stick (in theory).

Booting Ubuntu might also be worth a try.

Yes, the fact an identical system has the same problem is interesting, particularly as someone else with a different Gemini Lake system managed to boot into LE 8.2.4 with 4.11.y kernel (though without graphics due to the older graphics driver, and was then able to update to a working system with one of these 4.14.y builds). The fact syslinux isn't starting smells like a BIOS bug or boot incompatibility of some kind, which might be specific to this particular system or BIOS.

One other thing to try is booting with a different gptmbr file in case the BIOS is configuring a non-standard boot drive. Try writing (using the LibreELEC USB-SD Creator) this image of my latest build to your USB memory stick - it's using gptmbr_f.bin as the MBR, see if you have any more luck when booting the installer.
