If your default OS has Hypervisor OFF, you could select option 2 to run Windows 10 with Hypervisor, allowing you to run Hyper-V virtual machines. In this example case now, as my default OS has Hypervisor ON allowing Hyper-V virtual machines to run (#1 in next screenshot), selecting No Hypervisor option (#2) allows me to boot to Windows 10 with hypervisor OFF to run VirtualBox or VMware virtual machines: On the list, find your current OS with identifier hypervisorlaunchtype autoĢ.5) Restart the computer. This tutorial will show how to setup your Windows 10 computer to run virtual machines regardless which hypervisor is enabled and virtualization software used.ġ.1) Open an elevated Command Prompt ( tutorial), run the following command:ġ.2) This shows a list of boot entries on your computer. Problem is that because Type 1 Hypervisor needs to be enabled or disabled at boot before the OS starts loading, it can't be toggled ON / OFF live when Windows is running. Windows is loaded first, and hypervisor only thereafter.Īn image from Wikipedia article Hypervisor shows the difference better than I could ever explain: Type 2, hosted Hypervisors run on top of the OS. When enabled, even the physical Windows installation on the host computer runs on hypervisor. Type 1 must be enabled even before operating system is loaded. This is because of the difference between Type 1 (native) Hypervisors and Type 2 (hosted) Hypervisors. Contrary to messages from Virtual Box and VMware it clearly tells the cause:

When hardware Hypervisor is disabled, VirtualBox and VMware virtual machines can be started, but running a Hyper-V VM shows an error message. When tried, an error message tells that VM cannot be started.īoth VirtualBox and VMware error messages are quite confusing, not clearly telling what the problem is. Virtual machines can be created and their settings edited both in Virtual Box and VMware Workstation, but their virtual machines can't be run. When a Type 1 Hypervisor is enabled, Type 2 Hypervisors (VMware Workstation, VirtualBox etc.) virtual machines cannot run. Microsoft Hyper-V is a Type 1 Hypervisor. To run virtual machines on Type 2 Hypervisors like VirtualBox or VMware, hardware Hypervisor must be turned off. When hypervisor is enabled at boot of computer, only Type 1 Hypervisors like Hyper-V can run virtual machines.
