title: Docker + Virtual Box = VT-x is not available (VERR_VMX_NO_VMX)
body: <p>I installed docker. During installation, it complained that you can't have two virtualization environments, and that it would make docker the primary one. I said: "OK."</p>
  
  <p>Now, I need to go back to enabling virtualbox. I uninstalled Docker, hoping it would put things back the way they were, but: no joy.</p>
  
  <p>How do I re-enable virtualization for VirtualBox now that docker is gone?</p>
  
  <p>Note: Virtualization bit is set / enabled on the chip.</p>
  
  <p>OS: Win10 Enterprise.</p>
