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 tried to upgrade Windows 10 from Windows 8.1 for a week before finding this thread.

    Thanks to the advice here...after the installation files downloaded, when the "Creating Windows 10 Media" screen popped up, I unplugged the internet cord.

    After primary installation, a screen popped up that said working on updates. Then I plugged my internet back in to let these updates download.

    Yay! It worked. :-)

    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.

    Worked for me, thanks. I have Win 8.1 Pro, on a Mic Surface (ironically). After a failed media creation tool upgrade, I ran it again from the \ESD directory it had created, then selected Not Right Now. Around 37% I heard a "device disconnect" sound from the computer, then at 73% it only stayed there for 2 seconds, then continued on. It's been continuing to install like a champ ever since. Let's hope 22H2 does not have these "updates" baked in.

    Leave it to good'ol Microsoft to make updates that break things. I thought they wanted everyone to upgrade to Win 10? Not when they're making it this difficult.

    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.
