I had a similar problem Alienware OS recovery Tool caused my system to completely crash during recovery. The recovery got stuck and that's when I understood that it was wrong. The solution was to visit the Microsoft site, where I created a USB boot key. I installed a clean Win10 and then slowly downloaded all the necessary programs from Dell. I haven't had any problems since then! I will never use Alienware OS recovery Tool again !!!
