VirtualBox and Hyper-V on Windows 10 PRO

I have recently installed Windows PRO. During installation of Hyper-V, it duly warns you that you will no longer be able to use VirtualBox. Which is true, because when I start a VM in VirtualBOx I get the message:


WHvCapabilityCodeHypervisorPresent is FALSE! Make sure you have enabled the 'Windows Hypervisor Platform' feature. (VERR_NEM_NOT_AVAILABLE).
VT-x is not available (VERR_VMX_NO_VMX).


Apparently all you need to do to re-enable VirtualBox is:


open CMD as Administrator
bcdedit /set hypervisorlaunchtype off

reboot your machine

To restore Hyper-V you simply run:
bcdedit /set hypervisorlaunchtype on
or
bcdedit /set hypervisorlaunchtype auto


I haven't tested yet but it should work IMHO



bcdedit is this https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/bcdedit-command-line-options
