I have been learning Docker recently, and I installed and enabled Hyper-V by the way. The virtual computer I created before using VirtualBox can no longer be used, and the VirtualBox error is as follows:



Shutting down Hyper-V and restarting it did not solve the problem. Finally, the following solution was found in the VirtualBox community:

  • Open prompt as administrator.
  • Type BCDedIt and press Enter to find the hypervisorLaunchType option and find it Auto
  • Type the command bcdedit /set hypervisorlaunchtype off
  • By restarting my computer, I can open my previous project in VirtualBox normally
