I was trying to revert my computer back to a week ago and it kept failing due to antivirus software not allowing it. I then uninstalled norton, because they're service is a complete joke(long story), and the computer wanted me to restart to complete the process i chose restart later. I then attempted to revert my computer again, this time to a revert point a few days before the one i had tried previously. When it attempted to revert norton tried to shut the computer down while reverting. I am almost positive this is the cause for not getting past the welcome screen now. The computer starts regularly except once it gets past the windows is starting screen the screen goes black and i can only move the mouse around. I also cannot hit F11 to access the revert the computer back to factory settings, I hit F11 but nothing happens. Anyone know what the problem is?
