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.

    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 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?
