    Windows 8.1 Pro x64

    Upgrade from Windows 8.1 to 10 fails with error code 80070005...

    I received notification that my Windows 10 reservation is now ready. After downloading and preparing to install through Windows Update, I receive a failure notice with error code 80070005. I have done some searching online, but have found sparse information on how to resolve this.

    I am currently on Windows 8.1 Pro x64. I have administrative privileges.

    For several months, I've had an ongoing issue when I run 'sfc /scannow', corrupt files are found, some of which it cannot be repaired. From the CBS.log file, I found these related to "utc.app.json". I was assured that when Microsoft sent out update for DiagTracking (KB3022345), it causes a false positive for file corruption. Therefore, I never did anything about this, and I haven't experienced any other issues.

    Also worth noting is that I currently have my boot SSD partitioned and configured to dual boot Windows 8.1 Pro and Linux. This all works fine, and I've been told this shouldn't be a problem for upgrading to Windows 10.

    I would like to do an in-place upgrade to Windows 10, not a clean install, so that I keep all of my software and settings as they are.

    Thanks for any help / advice!

    Nothing to do about this?

    I also want to mention that I have my boot SSD as a GPT disk with an EFI partition. I just use the GRUB2 bootloader. I've read that others have upgraded dual boot systems to Windows 10 without issue. Generally one just needs to edit the Windows entry in GRUB2 so that it states, "Windows 10".

    I'd really appreciate any thoughts on how to proceed. Thanks again.
