Can't install Windows first time

I can not install Windows.
I have bought a herobox 256 and I get a message that Windows is not installed. Than to install Windows, click “ok” and the installation will restart. It’s an eternal loop… I’ve been there for hours and it’s always the same. What should I do?

Saludos!
