I have downloaded NOOBS onto a 32GB samsung sd card. After powering up PI for a brief period it shows the option to select Raspbian OS or another but before I can select any it continues to reboot with the error ... not a ISO3166 code.
Download 'Raspbian Stretch with Desktop' and flash that direct to your sd card using Etcher.
