    I could not update win10 to 2H20 after trying everything suggested. I was getting error code 0x80070003 .

    I dual boot Win10 and Linux Mint each on a different HDD with Linux giving me the option to boot up on the OS I choose.

    To solve the problem i had to make Win10 the automatic boot OS.

    I booted to Linux and used the program "G PARTED" to option Win10 as the boot OS.

    I ran "Win10 Update Assistant" and it worked.

    I now have the 2H20 update.

    I hope this helps somebody

    I had my updates paused, so nothing was downloaded or pending install. I did not turn off any of the virus protections running, or any extra steps like that.

    I then checked the hard drive for errors as mentioned above...

    1. Open a CMD window as an administrator.
    2. Type or paste ‘chkdsk /f /r’ and hit Enter.

    This said it couldn't run right no, but would do so automatically on the next re-boot.

    Before rebooting, I downloaded and ran the utility found here...

    https://www.microsoft.com/en-us/software-download/windows10

    The install took under an hour and had no issues. It required one reboot.

    Then I un-paused Windows Update and let all the mandatory updates download including our problem 20H2. Once everything was "pending install" I rebooted when prompted and waited for the usual failure message... BUT IT WORKED! Windows Update now has the "You're up to date" message and hopefully it stays that way for awhile!

    There is still one update sitting in the "Optional quality update" list...

    "2021-03 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5001649)"

    ...But I'm not going to touch it!

    Hopefully this solution works for others as well.

    This worked for me, after the System File Check. I was surprised at how many issues were repaired.

    First check the hard drive for errors.

    1. Open a CMD window as an administrator.
    2. Type or paste ‘chkdsk /f /r’ and hit Enter.
    3. Allow the process to complete.

    Then perform a system file check.

    1. Open a CMD window as an administrator.
    2. Type or paste ‘sfc /scannow’ and hit Enter.
    3. Allow the process to complete.
