Not again!

Yesterday I mentioned that I had reinstalled Windows to get round a problem with running Capture One and Affinity Photo, but that doing this had resolved the problem. This was optimistic. After taking the night off, I went on to reinstall some more applications, which all went fine, and I took another break. Then when I restarted the computer again it failed to boot, and I ended up with this message. Everything I tried just ended up with this screen, so I had to start reinstalling Windows and all the applications again. If this happens again I shall just give up on Windows altogether and will have to rely on the 7 year old Mac, which is slow with newer software or won’t run it at all.
