I am trying to install kali using VirtualBox 6.0 and on a Windows 10 machine.
I've tried using the VirtualBox image, the regular Kali ISO. I've disabled the Hyper-v before running the VirtualBox.
Using Hyper-v I can run Ubuntu and the Command Line Version of Kali (From the windows store). No matter what I do I get the same error message. I've included a screenshot
