Currently I am working on update our Windows 7 Master with integration of Internet Explorer 11, .NET Framework 4.6 and the new SP2 (W7).
I have an error 31 during deployment (step : OSConfigurationPackage) :
Setup Failed, Return value was 31
Setup Failed, Return value was 31 (Error [0x0604c3] IBS CallBack_ValidateAndPrepareInstallSystem : ComplianceRemedyPlugins() failed).
I encounter this error when integrating some Windows updates and random problem (It works on a computer model and not another model).
The error message on the PC : BOOTMGR is missing. Press Ctrl + Alt + Del to restart.
