THANK YOU! THANK YOU! THANK YOU! I spent 2 days trying so many things to fix this, but your suggestion did the trick! In case anyone is wondering, turn the internet off when it reaches the blue screen, before you start the actual install.

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.

Upgrading 8.1 to 10.
Always failed at 73%. I simply disconnected my internet, now it worked first try.
