NUC can't boot from a USB drive, stuck in BIOS menu

[LFlor9]

I have a NUC8i7BEK with Bios v72 (brand new)

I created a boot USB drive with Rufus, stick it in a back port. I press F10 and go to the BIOS menu. There I see the USB drive as a choice, it says:

UEFI : USB : USB Flash memory 1.0: Part 0: OS Bootloader

I scroll to that, press enter, the screen blinks briefly, then I am back to that same menu. I can select other boot options, that works fine. But I can't make it boot from my USB stick.

I bought another stick (scandisk USB 2.0), same result

I used rufus, unetbootin, UUI , same result (partition scheme MBR, FAT32)

I tried on another NUC, same result

unselected secure boot in BIOS

running out of ideas, any suggestion is welcome...

Are you trying to install Windows? If so, follow my procedure here (and do not use Rufus):
