  2. 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

    What are the details for that?

    "Windows 10 couldn't be installed - we could update the system reserved partition"

    I think you mean "could not update", not "could".

    Suggestions:

    • Disconnect any other hard drives.
    • Run chkdsk /f on the System Reserved partition. You'll have to do this from the CMD prompt in Repair Mode.
    • Initially there were reports of some System Reserved partitions being too small for the upgrade. Search for details if the first two suggestions fail.
