Hi, I'm having the same problem with my samsung tab 3. In order to stop it looping and be able to enter windows and do a backup. When at the blue screen where it says your computer couldn't be repaired click on advanced options, troubleshoot, advanced options,
startup settings and then restart. Once the system has restarted you will be at a blue screen startup settings. You are presented with 9 or so options. You need to select the option that says disable driver signature enforcement. This works for me and I can
use the computer but it doesn't solve the problem completely but allows you enough time to do a recovery. I have to do this every now and again because I refuse to restor, it gets you on to windows at least. Still looking for an alternative fix that doesn't
require a factory reset and will post update as soon as I can. Hope this helps, have a good day
