Immediately after starting a VM in VirtualBox, I receive a error box that contains the following error message:

Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).

I am running Windows 10 Professional, Version 1903 and have confirmed that Hyper-V is not enabled.

  • Are you running Windows 10 Professional? – Stevoisiak Aug 6 '19 at 15:38
  • I got the same problem and none of the solutions from here doesn't work for me. Could you please take a look on my question - superuser.com/questions/1508514/… – KozhevnikovDmitry Dec 9 '19 at 7:17
  • I don't have enough rep on this SE site to post this as an answer (perhaps someone else would though?), but I just managed to get my VMs to launch in VBox 6.2 on a Win10 Pro 1903 host with both "Hyper-V" and "Windows Hypervisor Platform" features installed: I just needed to update my VBox global config with VBoxManage setextradata global "VBoxInternal/NEM/UseRing0Runloop" 0. See this VBox forum post for details. – user293915 Jan 29 at 11:10
  • Minor correction to my previous comment (too late to edit it now): I meant in VirtualBox 6**.1**.2.. – user293915 Jan 29 at 11:39

Open the "Turn Windows features on or off" settings (type optionalfeatures in the start menu or Win + R), and untick "Windows Sandbox". A couple reboots may be required.

This is a new feature in Windows 10 v1903 that uses Hyper-V on the backend (even if it's not enabled in Windows Features), which makes this feature not compatible with VirtualBox.

  • I am also facing this same issue. In my machine both hyper-v and sandbox not enabled (both are untick). Any other suggestions? – PSR May 30 '19 at 8:03

    Two reboots are needed after disabling Windows Sandbox – Jonathan Rioux Jul 13 '19 at 2:13

    In my case was unchecking "Windows Hypervisor Platform" – user63227 Jul 23 '19 at 23:10

    The "Windows Sandbox" can't appear for some people that are not using Windows 10 on english language (my case, I'm using Brazilian Portuguese). On that case, you can use the command line to disable it: Disable-WindowsOptionalFeature -FeatureName "Containers-DisposableClientVM" -Online – Dherik Sep 13 '19 at 17:44

    It seems that Microsoft is re-enabling Hyper-V even if we disable it with those feature updates. (Hyper-V was re-enabled on my Windows 10 PC after upgrading to 1903 without telling me...) – Bajiru Dec 1 '19 at 9:40

Finally solved the issue.

  1. Turn off Hyper-v
  2. Turn off Windows sandbox

by navigating to "Turn windows features on or off".

Restart the machine twice and then try to Start vm in virtualbox.

    Restart twice EVEN if Windows sandbox was already off and only Hyper-v was turned off did the trick! – Frithjof Schaefer Sep 12 '19 at 15:05

    Also turn off "Containers" – nimrodm Feb 19 at 14:14
  • Double reboots helped me! – Feanor Apr 2 at 9:19
  • worked for me too! thank you, life saver! – petrosmm Sep 18 at 19:38

According to this VirtualBox forum post, there are several features which might use Microsoft Hyper-V, which is not compatible with VirtualBox:

Look in the "Control Panel" » "Programs and Features" » "Turn Windows features on or off", and make sure that the none of the following are active:

  • Application Guard
  • Credential Guard
  • Device Guard
  • <any> * Guard
  • Containers
  • Hyper-V
  • Virtual Machine Platform
  • Windows Hypervisor Platform
  • Windows Sandbox
  • Windows Subsystem for Linux (WSL)

If that doesn't work, enter the following command:

bcdedit /set hypervisorlaunchtype off

followed by a cold boot, i.e. shut down the computer, pull the power plug for 10 seconds, reboot.

For me, just disabling "Virtual Machine Platform" and restarting TWICE made it work.

WSL 1 will still work. I'm not so sure about WSL 2, which is currently available in the Windows Insider Program.

  • I can confirm that "Virtual Machine Platform" feature is required for WSL 2 Also mentioned here docs.microsoft.com/en-us/windows/wsl/wsl2-install – Boris Brdarić Jan 15 at 0:42
  • In my case, I had to uninstall Windows Defender Application Guard and reboot. Other solutions did not work. – claytoncarney Mar 7 at 19:22
  • Yep, I've just enabled "Virtual Machine Platform" to try WSL2 and VirtualBox broke. Disabling the component and restarting the notebook twice brought VirtualBox back to life again. – Alex Che May 5 at 12:54

In my case, turning Windows Sandbox and Hyper-V off and restarting my PC dozens of times didn't work. I even tried turning the features back on, then back off, then restarting another dozen times.

What did work, was disabling Memory integrity from Core isolation in Windows Security, possibly because it uses virtualization features, as do Hyper-V and the Windows Sandbox.

Now I can finally start my VMs again.

Hyper-V needs to be disabled but not uninstalled. I wanted to maintain Hyper-V functions some of the time and have the option to reboot into windows with Hyper-V disabled.

I ran the following in an administrator powershell prompt:

bcdedit /copy {current} /d "Windows 10 no Hyper-V"

The entry was successfully copied to {95524711-fa90-11e9-b0c8-927c2d2c6eb6}.

Copy the GUID into the next command:

bcdedit /set "{95524711-fa90-11e9-b0c8-927c2d2c6eb6}" hypervisorlaunchtype off

The operation completed successfully.

Click restart while holding the shift button And keep holding shift

Select "Other Operating Systems" and your "No Hyper-V" option is in there.

If you want to change the default mode (either with hyper-v enabled or disabled), run msconfig and change the default on the boot tab.
