Please help - my NUC freezes when I boot from USB and my googling has failed me.
I bought a NUC5i3RYK, installed brand new RAM and SSD (not NVMe), updated the bios, flashed hassio to a USB drive using Etcher, but the NUC freezes when I boot with the USB plugged in. I get some very brief output and then a blank screen with just an underscore at the the top and the functions legend at the bottom (press F2 for setup, etc.), except it’s frozen.
This was briefly printed before freezing:
Bootchooser: No valid targets found.
Nothing bootable found.
Maybe something went wrong with Etcher, even though it said success?
