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 didn't get the option to choose. However when it started to download windows 10 updates, I disconnected the internet. Then it worked fine.

    When did you disconnect the internet during the download?

    I don't remember exactly. Try before the window turns blue. The idea is to stop windows from updating during the installation process.

    How did you know exactly when it starts to download updates? For me it is only "Downloading Windows 10" without pointing the difference between base OS and updates, so I have no idea when to cut the connection.

    I use Media Creation Tool -> Update PC(when I get to choose whether to update pc or prepare ISO image) -> downloading -> verification of downloaded data -> etc etc etc

    I don't remember exactly. Try before the window turns blue. The idea is to stop windows from updating during the installation process.

    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.

    This worked for me! Thank you so much. For those of you who want to try this method, here is what to look for:

    When you are upgrading to Windows 10, one of the first screens that you see is titled "Install Windows 10". This has a paragraph explaining updates. Look below this paragraph for the link (in blue letters): "Change how Windows Setup downloads updates". Click on this link.

    This brings up a screen titled "Get update, drivers and optional features." Select the "Not right now" option.

    This way you can do the upgrade without first downloading the updates. If the upgrade is successful, then the follow-up updating can take place. In my case this updating began automatically, and it took quite a while, more than one hour.
