All
I customized my reference pc to which I was happy to make a WIM file. Took the image via DISM and wanted to install a new pc.
I have made 3 partitions:
1. BOOT 500MB
2. Windows 100GB
3. Datadisk 50GB

Weird part is that i don't know where to retreive the boot WIM, thus my windows 10 installation is clearly not booting. Please help. Do I need extra partitions, what am I doing wrong, this was always the way I did it with Windows 7
