After a lot of tries, I figured out how to install windows 10 on my raspberry from a windows 8.1 VM:
- USB reader.
- 16 GB micro SD card.
- Raspberry PI 2
- Install windows 10 ADK technical preview (https://go.microsoft.com/fwlink/p/?LinkId=526740) on windows 8.1 VM.
- Navigate to the installation folder which in my case was “C:\Program Files (x86)\Windows Kits”, then navigate to 10\Assessment and Deployment Kit\Imaging and Configuration Designer\x86
- Run ICD.exe app, click deploy to removable device open flash.ffu file, after that select your micro sim card.
