    Win 10 Pro to Win11 Pro migration: "We couldn't update the system reserved partition"

    We couldn't update the system reserved partition - Windows 10 1803 Updates won't install

    The usual suggestion is to clean it out.

    https://support.microsoft.com/en-us/help/3086249/we-couldn-t-update-system-reserved-partition-error-installing-windows

    Are you implying DISM is showing a message about bootmgr? What is the message exactly? You may need to use a different DISM syntax and point to a /source:

    Otherwise it may be bogus. For a possibly related incident see

    https://answers.microsoft.com/en-us/windows/forum/windows_10-update-winpc/windows-10-update-kb3213986-fails-repeatedly-with/46d9b1af-71a6-4d39-acaf-c3882047ac12

    What are the details for that?
