Windows 10 won't boot with bcdedit hypervisorlaunchtype auto

i'm trying to run a virtual Linux on my Windows 10 Pro Maschine using Hyper-V. In order to start that VM i have to enable the build in Hyper-V Hypervisor. The problem is that as soon as i run "bcdedit /set hypervisorlaunchtype auto" Windows doesn't boot at all. There is the usual POST screen, after that the Windows Logo appears for a short period and then it blacks out and the POST Screen comes up again.

The only way to start Windows is to boot to safe mode and set hypervisorlaunchtype to off.

I copied my bcdedit below if that helps. I have a Intel Xeon E5-2670 CPU on a X79 Mainboard and VT-D and every other virtualization feature enabled.

Thanks in advance.
