VirtualBox causes host BSOD starting VM under Windows 10. Hyper-V is off

Solution 1:

As it turns out, disabling Hyper-V is not enough. There is another Windows feature, called Virtualization Based Security, that employs Hyper-V. You need to disable that as well.

All I needed to do was to change one registry key and reboot:

Use regedit to set

HKEY_LOCAL_MACHINE\SYSTEM\Software\CurrentControlSet\Control\DeviceGuard

to 0, and reboot.

There is a nice description of Device Guard / Virtualization Based Security here: Windows 10 Device Guard and Credential Guard Demystified.

Solution 2:

Have this issue on the new Windows 10 Fall Creator Update (1709) build 16299 and Virtual Box. Both VirtualBox versions were tested also: - Version 5.1.26 r117224 (Qt5.6.2) - Version 5.2.2 r119230 (Qt5.6.2) HyperV features are NOT deployed but by default, MSINFO32 shows up "Hypervisor enforced Code Integrity" on the new Fall Creator Update build.

Result from MSINFO32.EXE

It looks like that this feature will lead VirtualBox to a BSOD.

You lucky guys, there is a fast and dirty way to fix this: DISABLE SECURE BOOT.

(Just to test!!! your security department won't like it) If I get a clean solution I'll post it ;-)

Cheers
