    Same issue here. ISO doesn't help and it seems that it is not a true ISO, just something to start the process (at least if installed on a flash drive.).

    The problem can be caused by partition manager.

    I had two laptops screwed up by easus todo partition manager which I am pretty sure caused by 80070003 errors. In my case I found this after I did a complete factory restore and then changed my HDD to an SSD. At this time my partitions were ok (after the restore). I then attempted to use the same software to do a clone in order to use the new SSD. The resulting non-os partitions looked wrong so I contacted their support and they agreed. I then used another clone software that came with my clone cable and the results were good. I sent those results to easus todo support. They acknowledged the issue but offered no solution. I sent the same results to the maker of the clone cable who noted that their software seemed to have fixed the partitions.
    My question is, why doesn't Microsoft know this?
