#20177 new defect

NtCreateFile(\Device\VBoxDrvStub) failed

Reported by: JochenW Owned by:
Component: other Version: VirtualBox 6.1.18
Keywords: Cc:
Guest type: other Host type: other


Did the following:

1.) Downloaded the latest 6.1 test build from, and installed it.

In VBoxHardening.log, this build is identified as

10.0.19041.662 (WinBuild.160101.0800)

2.) Created a new, blank VM, and attempted to boot that VM via the Iso file


3.) Started the VM, got the error message

1d38.32f4: NtCreateFile(\Device\VBoxDrvStub) failed: 0xc0000034 STATUS_OBJECT_NAME_NOT_FOUND (0 retries)

Driver is probably stuck stopping/starting. Try 'sc.exe query vboxdrv' to get more information about its state. Rebooting may actually help.

I'll attach the VBoxHardening.log.

No need to create a separate ticket for this, do you have by UEFI Secure Boot enabled by chance? Testbuilds don't work with it as stated here.

comment:2 by JochenW, 3 years ago


    they will not work (the error message will point to unsigned drivers) ... if your system
    has UEFI secure boot enabled

Have to admit, I didn't consider that to be applicable here. In the log file, there's nothing with "unsigned".
