I have a Lenovo Yoga2 Pro running build 10074. I can't enable Hyper-V and need it for some Visual Studio Phone development. It allows me to add that feature, and "configures" windows, reboots, says it is finishing, gets to 95% and fails. Then it backs out the changes, reboots and I am back where I started.
I do have Hyper-V working on my desktop also running 10074 and it works fine with Visual Studio 2013. I also have virtualization enabled on the Yoga2, and had this working on an earlier build. The upgrade to 10074 did fail and I was forced to use the recovery disk to do a "clean" install of 10074.
Any pointers would be greatly appreciated.
