I hope someone can help. After re-booting my Asus laptop the other day, it took ages to re-start and I got as far as the desktop which looked normal, but none of the applications or programs would open. I kept getting Application Error message boxes popping up. I can't even open Settings. I can get into File Explorer. I tried to perform a clean boot using the Media Creation tool but it just took me to a black box stating Missing Operating System. I've tried re-starting several times, and sometimes I don't even get as far as the desktop, just a grey screen with the white cursor, which just hangs. Can anyone shed any light?
