I was given a used SP3 that wouldn't boot into Windows. I downloaded the Recovery Image and it failed to install W10. It has been so long, I don't remember the error. So I installed linux, just to see if it would the machine worked and it installed fine, things like touch and a few other things didn't work, So I downloaded a copy of W8.1 and it installed fine. It appears the WIFI card no longer works. I've tried installing a vanilla W10 a couple of times and received a different message each time. One of the messages was the image was incompatible with the SP3 and the other was the watchdog error. I've also tried to upgrade from within W8 and that fails also. I believe the problem is the WIFI card. Is there any way to edit the W10 image to maybe remove the wifi driver? Or is there a way "force" the install somehow? W8 works fine it's just that it is no longer supported and I can get any new apps from the marketplace.
