Can't revert to using Virtual Box after using Docker on Windows after latest update

I have been running Ubuntu in a VirtualBox machine. I could always switch between using Docker and using VirtualBox by turning off Hyper-V windows feature in Control Panel. However, after Windows 1903 update I tried switching back to VirtualBox, same as before, but I got ERROR_SUCCESS (Last=0xc000000d/87 (VERR_NEM_VM_CREATE_FAILED). This error is the same everyone gets when they haven't turned off Hyper-V in Control Panel.

Has anyone else encountered this problem and does anyone know a simpler solution to switching between VirtualBox and Docker that would not be affected by future OS updates ?

windows
docker
ubuntu
virtual-machine
virtualbox

The following 3 steps worked for me:

  1. Run CMD (as Administrator) to open a terminal
  2. In the terminal, type bcdedit /copy {current} /d "No Hyper-V"

You should get a message of the form: The entry was successfully copied to {ff-23-113-824e-5c5144ea}.. Of course, ff-23-113-824e-5c5144ea is an example of identifier in this example. You'll get another one.

Finally, use this identifier to run the following command:

  1. bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off

You should get a message of the form The operation completed successfully.

I got this from SwitchEasilyBetweenVirtualBoxAndHyperV.
