Using my Macbook Pro on OS Mojave, starting up Windows 10 on Parallels 12 gives me the prompt "Your PC did not start correctly. Press "Restart" to restart your PC, which can sometimes fix the problem. You can also press Advanced Options to try other options to repair your PC." I tried to system restore and it did not work. Resetting the PC does not work as it says "there was a problem resetting your PC. No changes were made.". I've also tried to start up using safe mode and safe mode with networking, and both routed me back here. Startup repair cannot find what is wrong with my Windows either.
