I'm trying to get a vagrant box for ubuntu and running on my windows machine, and every time I type in "vagrant up" I get a BSOD. I've turned off Hyper-V in windows as this was the suggested fix. The issue is still there.

The error code I see in the VirtualBox logs is as follows:

00:00:05.633668          ERROR [COM]: aRC=E_ACCESSDENIED (0x80070005) aIID={4afe423b-43e0-e9d0-82e8-ceb307940dda} aCompo
nent={MediumWrap} aText={The object is not ready}, preserve=false aResultDetail=0

The file from a crash analysis is linked as follows:

I'm currently running Virtualbox 5.2.2 and vagrant 2.0.1 on a Windows 10 machine.

Does anyone know how to work around this?


  • What d you mean you have tried turning off Hyper-V? What does your setup look like? Why Hyper-V and VirtualBox?

  • @Seth About Hyper-V, I've unchecked it as a feature in windows. Also what do you mean by setup? Are you referring to my hardware?

  • Do you have a minidump file under \windows\minidump\ from the bugcheck? If so, maybe send it to osronline.com/page.cfm?name=Analyze. You could Pastebin the results and link it here. Dec 12, 2017 at 21:41

This is because of the Virtualization Based Security feature that Windows has from 1607 onwards.


Check msinfo32.exe (System Information) and scroll to the bottom of your system summary. If you see "A hypervisor has been detected..." you're in secure mode and can't run other virtual environments without crashing windows.

Use an admin cli and type the following:

reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard" /v "EnableVirtualizationBasedSecurity" /t REG_DWORD /d 0 /f

Restart the machine after this and check the system information again. You should see something like the following image:
