But when I want to dual boot, I need it to really shut down and give me an option to chose this new boot menu. On my Lenovo it starts in about 3 seconds, faster than I can press any buttons to interrupt it. In Windows 8.x, Windows is optimized to startup FAST. C:\>bcdedit /copy hypervisorlaunchtype off Note the first command gives you a GUID and you then copy it and use it with the second command.
Instead, from an administrative command prompt I made a copy of my boot menu with a 'No Hyper-V' entry: Some sites say to use Add/Remove Features to turn the Hyper-V support off, but that seems like a big deal to do what should be a small thing. GenyMotion use VirtualBox, which has it's own Hypervisor and you can't have two.
However, I also use Hyper-V when developing for Windows Phone.
I've been using GenyMotion for a FAST Android Emulator when developing with Visual Studio and Xamarin.
