Can't start my virtual Box machine after installing Docker on Windows

Question

To learn ArchLinux, I installed and using ArchLinux in a VirtualBox machine. It runs perfectly. Now I installed Docker on my pc (Windows environment). During the installation of Docker I got a warning, that if I install Docker on Windows, that VirtualBox cant boot my machine's anymore cause of ...

I uninstalled Docker and hoped that I could still use my ArchLinux. But I cant!

Do anyone know what to do, to run VirtualBox and the machines inside correctly again?

VirtualBox can't run anymore because Docker for Windows activates Hyper-V during its installation (with your permission). So you have to disable this feature again. You have to uncheck Hyper-V in Control Panel -> Programs -> Programs and Features -> Turn Windows features on or off. After a reboot, VirtualBox should be able to run again.

I also needed to disable Hypervisor like described here: https://stackoverflow.com/questions/50053255/virtualbox-raw-mode-is-unavailable-courtesy-of-hyper-v-windows-10 – Line Sep 20 '19 at 12:49

I had the same problem.

I just due to changing Hyper-V Launch Type using BCDEDIT.

You can try setting the launch type to Off by running the command below:

bcdedit /set hypervisorlaunchtype off

Please see this post => How to Disable Hyper-V Completely in Windows 10

This command fixed it for me. But open Powershell with admin rights and then run the command. – Olivier Van de Velde Jan 01 '21 at 10:02
To turn it on again use `bcdedit /set hypervisorlaunchtype auto` on a terminal with root access and reboot. – Nima Bastani Jan 17 '21 at 18:14
You also need to restart your PC so changes take effect – Sergi Feb 25 '21 at 16:56

I could not start my virtual machines after turning off Hyper-V Windows feature as well. I had to repair my VirtualBox installation using the VirtualBox Setup. – Tobias Roloff Oct 17 '19 at 08:52

You have to uncheck Hyper-V and Virtual Machine Platform (if checked) in Control Panel -> Programs -> Programs and Features -> Turn Windows features on or off. After a reboot, VirtualBox should be able to run again.

This is similar to the most popular answer but adds "Virtual Machine Platform" which is what mattered for me – WiringHarness Apr 28 '22 at 18:19
