    Hi, I would suggest doing a clean boot, make sure any AV is disabled, then try the upgrade.

    However, note the error is
    "The installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation."

    I'm wondering if you've relocated any user data folders or made any changes to Windows normal data structures.

    You could also try running
    chkdsk C: \F
    from an elevated command prompt to check file structure integrity.

    My upgrade worked with Avast installed. (Whereas upgrading from Win 8.1 with Bitdefender installed left me having to uninstall and reinstall a different version).

    You've chkdsk and the clean boot to try, failing other advice.

    Make sure you've disconnected any external devices you don't need, and have nothing unusual in terms of your disk configuration in your PC (e.g. dual booting, a disk with a previous Win 10 on it... ).

    This is helpful and clear:
    Fix: Windows 10 Upgrade Stuck at 75% or 76% - EaseUS

    You've probably seen this:

    Note suggestion of 'some driver incompatibility'... have you any less common programs that you can readily uninstall that either
    - change or modify the GUI
    - install drivers

    You might think there would be a log of what happened- I've not had to look for this, so maybe someone can suggest where to look. E.g.

    (I have a lot of programs installed and whilst 4 proved incompatible, only one- and that was no surprise- affected Win 10 running after installation).
