UEFI Client PXE Boot error fails with BSOD: Unmountable_Boot_Volume

Hi experts

When I try to boot my uefi client from LAN it successfully downloads boot.wim from my WDS 2012, shows the Windows Logo for some seconds, but then it crashes, showing BSOD and the message "UNMOUNTABLE_BOOT_VOLUME".

I'm using the same x64 boot.wim as with the BIOS clients, but with the mbr clients it works.

What is it, that makes my boot.wim unusable for uefi clients?

I always use the system's boot menu and manually select the UEFI option just to be sure.

If you are doing a PXE boot, usually the screen changes aka text/screen area becomes smaller than if you do a legacy boot.
