Thank you Angie for your input...
I did try the recovery methods mentionned (jumper), and they worked... until the reboot !
I actually found the real problem, as I took the unit to the bench and hooked it up only to a screen and keyboard/mouse : it just would not boot with two screens (miniDP and min-HDMI) attached ! It ran fine if I connect the second screen after boot-up, which is kind of a pain, but I cannot yet find the energy settings in the Bios that would fix that...
The NUC had been running fine with two screens for years (since 2013) with the original bios, until I had that unfortunate idea to upgrade it, as I figured it would be better suited for windows 10 operation...
In short, my immediate problem is solved, but I would welcome suggestions for bios settings to fix that
The NUC config :no wifi/BT card, just a 120Gb mSata ssd and 2x8Gb Sodimm RAMs.
Thks again anyway !
I've no idea what is wrong in your Bios settings (may be wrong aperture size? or other graphics memory settings?). Any way the best way to fix wrong bios settings, is to set them back to default settings.
To do this, enter Bios settings (press F2 when F2,F7,F10 menu appears during boot process). Then press F9 to bring back Bios defaults and finally press F10, to save those settings and exit from bios screen.

Please let me know your findings.
my last post stands. The new bios (42 and 43) work fine, with ONE screen at start-up. The second screen works fine if connected after boot. Of course I reinitalized default settings, etc. No change.
I really don't have time to look further into it. I simply connect the second screen after boot, and that's it.
Thank you everybody.
1. On 12/14/2016 a new Bios 0044 was released. Try to update your NUC. Download BIOS Update [WYLPT10H.86A]
2. In Windows, check in Intel Graphics Settings->Display->Multiple Display settings.
3. Verify that you have the latest drivers. For example Chipset ver 10.1.1.38 dated 10/31/2016 Download Intel® Chipset Device Software for Intel® NUC and Graphics driver.
