    Yeah, made an image before trying to update. Will try that albeit all others I upgraded successfully had the same antivirus installed. (it's the go.to version here, as it's free and pretty good detection rate).
    Yes, please remove those programs, post a screenshot of disk management and run scf /scannow on the system.
    Will wait for your reply.

    It's a well-known fact that upgrading with a 3rd-party AV installed is asking for trouble, especially when upgrading a W7 rig. You got lucky on the other ones. I like Avira a lot, but it needs to go for the upgrade.

    Please post the disk management screenshot. I have found some W7 rig's System Partitions (NOT Operating System partitions) to be too small for the upgrade's rollback settings.

    So Now after over 36 hrs I hard rebooted and as expected it rolled back to 7 is it did before. i was presented with this error:

    0x0900101 0x4000D

    With a message roughly translated:

    During phase SECOND_BOOT during procedure MIGRATE_DATA and error occurred.


    Google gives 2 hits, one of the a youtube video un russian (?) that shows many errors includign this one but I don't speak russian.

    So I will uninstall some apps I installed since last fall were the upgrade at least completed.
    See here:
    Windows 10: Upgrade-Fehler 0x8007002C-0x4000D | Borns IT- und Windows-Blog

    If you don't read German, you can use Translate in Chrome for English.

    The explanation: A required file is missing or damaged (because the filter driver of AV software, the USB devices or other system tools block there). And the winner is? Antivirus software

    scannow find no issues.

    About partitions. Not at home right now. Will update later.

    But remember the upgrade worked for me last Fall and nothing changed in terms of partitions since then. I reverted because it was unstable.

    Okay, that's true - partitions shouldn't be your problem then.

    Instability can be caused by upgrading with a 3rd-part AV installed.

    Hmmm....not enough partitions there....
    Do you have Macrium Reflect Free on the system? A screenshot of your partitions from that may be better. It will show everything for sure. But, it looks to me to be a problem. Did you have more than one drive connected to the system when you upgraded the first time?

    Unfortunately, I will be AFK most of the day today. Perhaps @f14tomcat can assist in my absense? What do you say TC?

    Drives where the same, yes. It's custom built so no recovery partition. What is missing?

    EDITT.

    macrium shows the same paritions.
