Disabling Device Guard or Credential Guard fixed for me:
- click Start > Run, type
gpedit.msc
, and click Ok. TheLocal Group Policy Editor
opens. Go toLocal Computer Policy
>Computer Configuration
>Administrative Templates
>System
>Device Guard
>Turn on Virtualization Based Security
. Select Disabled. - Go to
Control Panel
>Uninstall a Program
>Turn Windows features on or off
to turn offHyper-V
.
Select. Do not restart.
Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:
mountvol X: /s copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi" bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215} bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X: mountvol X: /d
Note: Ensure X is an unused drive, else change to another drive.
Restart the host. Accept the prompt on the boot screen to disable Device Guard or Credential Guard.
