Did you find a solution to this? I have chatted with 2 different techs through their help chat and neither one is able to help me. Mine is also failing at 73% no matter what.

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.

2021-12-22T02:22:52+00:00 I bought the upgrade to Windows 10 and I am getting the same thing. Microsoft is corrupt. They will not give you a refund or the help needed when they sell you something. You would think that the laws on merchantability would apply here. Microsoft does not care. They are only about the money. And their support center in West Nigeria is pretty much useless.

2021-12-12T17:06:41+00:00 My system is running WIndows 8.1 *Home*, not *Pro*, and yet my attempts to upgrade to Windows 10 fail at exactly the same "73%".
I have run Windows Update until there are no more updates, have more than enough storage space on the hard drive, have memory that passes all tests, have a CPU that is more than fast enough for Windows 10, and I am trying to upgrade from a DVD with the latest ISO burned to it to upgrade. No matter what I try, all attempts fail at "73%". It seems to me that this is consistent for enough of us in the Microsoft Windows community that someone at Microsoft should be able to tell us what to look for in our systems to try to get past this.
