I partitioned my hard drive and installed Debian on second partition. In order to do this I had to switch from BIOS to UEFI after basically destorying the MBR. Everything works great. However when I choose to boot to Windows 10 my various images within Hyper-V are not starting. The error states that hypervisor is not running. Any ideas?

I tried this Hyper-V reports that the hypervisor is not running. How to start the hypervisor? but no joy. Any suggestions on why this would have stopped working?

Turns out running command prompt as administrator and running bcdedit /set hypervisorlaunchtype auto followed by a reboot did actually work. I stopped and started the service using the controls in Hyper-V Manager. My VM was in a saved state. This reset itself. My actions above followed by a second reboot seemed to do the trick.

One additional step was that I downloaded EasyBCD and checking through the options confirmed that Hyper-V support was enabled.
