Using etcher to flash latest hass.io image before booting my NUC. Latest bios is installed on my NUC. When I power on my NUC and boot from usb I am getting the message ‘reboot and insert a proper boot device’. booting another image works just fine.
Just yesterday I spent half day to understand why I couldn’t flash the image as the first time.
Perhaps I changed something that I had to download the image again.
But when I checked the two image the md5sum were the same. The only thing I’ve done it was to repack the image with 7zip, which saved 25% of the space.
I don’t understand whether that would affect something.
