    Thanks SM. The problem is a bit bigger than we think. Apparently, the boot configuration data is corrupt.

    In my experience, Rebuilding BCD using  Command line from a USB installationn often helps.

    Please boot to advanced startup options from a USB drive

    In case, you need to create a bootable drive:

    Then rebuild BCD using these instructions:

    Hello,

    In the last suggestion....

    My solution is to remove the BCD and build a new one instead of repairing it. Boot into recovery and then command prompt. Use DiskPart to select the EFI volume (the 100MB hidden partition), assign it a drive letter like "v". Go to the EFI volume and directory v:\EFI\Microsoft\Boot\ , and rename the "BCD" file to something else. Run "bcdboot c:\Windows /s v:" to recreate the BCD file (your system drive may vary). Make sure the "\EFI\Microsoft\Boot\BCD" is there and reboot the PC. Try Windows update again

    Where should I look for the EFI volume in my configuration?   I used a bootable USB installation to attempted the repair but did not try the command line approach.

    Here's what I have configuration wise....  Repair Log Files

    Hi SM, As I see from the diskpart, volume 7 is what would have the EFI files.

    Volume 7     F                NTFS   Partition    517 MB  Healthy    Hidden  

    If you want to skip all of this, the easier route is a reinstallation of Windows. It would cost you the installed apps though.
