Can't figure out what's causing it. I tried using the 1903 media installation tool but I get the same problem with that too.
My pc would upgrade to 1903, neither, but I found the cause. It was a very old installation of TotalMedia that caused a BSOD. Uninstalled it and the upgrade went through without a hitch. Remember to uninstall the driver for total media as well(!)
I found out this was the problem as I analysed the .DMP file produced during the installation. Do note that this is not the path: C:\Windows\MEMORY.DMP, but rather a path into the temporary/new windows installation C:\$something\somepath\somefile.DMP
Once opened with WinDbg, one commant (bt for back trace) shows the stack dump and the last entry is where it crashed. It should be easy enough to see if it crashes in a SYS file and which.
