Help with "Windows 10 installation has failed" at 73% on Windows 8.1 Pro

Every time I try to install Windows 10 through the Media tool I always stop at 73%. I tried to do it on a Clean Boot and it was the same. I also tried to remove the "read-only" and "system" attributes on the "$WINDOWS.~BT", but it doesn't let me change the "Read-Only" attribute on a file called boot.sdi and I don't know how to remove the "System" attribute.

    I had the same problem. There is a dialog somewhere at the start of the install process that gives you the option to install Windows 10 without updates. I tried installing again, this time i chose to install Windows 10 without updates. It worked for me. After my computer rebooted, updates started installing automatically anyway. There was a minute when the screen went black, so if that happens to you don't freak out. It will come back on. I hope this works for you.

    Not sure what's up with the serious duplicated posts in this thread lol.

    But, if you already had Windows 10 on the computer, you can just download the Windows 10 iso, burn that to usb stick, and clean install. It would already be recognized as authorized.

    If not having it previously, it could take some doing to workaround the issue. But, it might just work to burn a Windows 10 iso then do the upgrade from that if you haven't. I don't use it but it should offer a choice to upgrade or clean install. That should offer the best chance. If it still fails then the Windows 8.1 install is corrupted (meaning it can't successfully upgrade it) or Windows 10 has some sort of compatibility issue with that computer or something attached to it (and thus same result).
