I am using Raspberry Pi3 Model B+ embedded card and I am trying to flash Windows IoT core.
I had some issues with it while it does not boot.
I followed the steps described here and used RaspberryPi 3B+ Technical Preview Build 17661 : RPI3 B+ IOT
But same problem occurs : stack in Rainbow screen.
I am using 16 GB Class 10 PLATINET micro SD. The SD is working fine with Raspbian.
Could anyone help me. Thank you!
