Hi, running: Parallels Desktop Pro Version 12.1.1 (41491) Mac OS X 10.12.2 MacBook Pro 13" 16 GB RAM Windows 10 Enterprise Version 10.9.14393 Trying to get Windows 10 working with Hyper-V for phone development. If I install Hyper-V after enabling the check box for nested virtualization and reboot my Windows 10 machine just goes into a cycle of reboots before trying to repair which doesn't work. If I remove the checkbox the machine boots normally. If I disable the checkbox, remove Hyper-V, reboot the Windows 10 machine then shut it down, then check the box to enable nested virtualization then reboot the Windows 10 machine will boot. If I then install Hyper-V and reboot, same issue. I've tried both fresh installations and repair and neither seems to be working. Is this supported in version 12 or do I need a hot fix for it to work like in Parallels 11? I specifically paid extra for the Pro version just to get this working so I could do phone development. Thanks Aaron
