An unofficial Debian Installer for Pinebook Pro

[User 19975]

Help needed

Forgive my noobiness, but I need some help.  I want to make the move from Windows to Linux.   I have used linux for a few years, but not seriously.  Now I am getting serious! 

I was gifted a Pinebook Pro for my birthday and am trying to try out different distris.  Machine was installed with Manjaro, but I wanted Ubuntu, so a friend of mine installed Armbian (on the emmc), which is really lovely, but I want to experiment with other distris on the sd.   

So, I cloned the Git repo for this script described here and it goes through the installation process, seemingly successfully.   When I go to start my machine, it just starts Armbian and ignores the debian installation on the sd card.  This is what I have done to test

• to make sure my sd drive is working correctly, I inserted the the copy of Armbian which was dd'd to my emmc.   It booted fine.  So SD is not the problem
  
• I thought that maybe it could be a dud card, so I tried another one, much quicker, that I know works and I get the same result, nothing and then boots from emmc
  
• I've mounted both SDCards and they were successfully written to
  

So, I am beyond my knowledge at this moment in time.

I would really appreciate some guidance here
