Hello,
Thank you all for your feedback.
The keyboard Up key worked to get me past the security prompt. I was able to install Android.
Best regards.Gabi

It is not a firmware message.  It appears to be an OS message or boot loader, saying that the system is not running as a secure boot configuration, and that the changes made (boot device) is not per the factory configuration of the product.  It is warning you that this could allow malware to boot on your platform (if the USB driver were contaminated with Malware) and since secure boot is not enabled (to check signing), there is no safety net for this possibility.  The message seems to be a courtesy telling you how to 'safety net' the system by turning on Secure Boot to ensure that only properly authorized code is executed from the non-factory boot device through secure boot mechanisms.  

Sincerely,


Michael Krau

Keyboard up arrow, as I'm led to understand, will get you past that.
I'll pass this missing bit in the 01.org docs along so that can get added.
