viBoot is dependent on the Windows Hyper-V to be activated in order to function.
When Hyper-V is enabled on Windows, Oracle VirtualBox and VMware with all associated virtual machines, don't work anymore.

Hi,

It is a limitation of Windows/CPU that you cannot have different hypervisors running concurrently.

If you want to support different hypervisors on your machine you will need to configure Windows to switch between them at boot time. Please see the following link that provides instructions on how to do this:
