I have a black screen with nothing just a glow and when I hold Ctrl-Shift-Esc the cursor pops up. I try to bring up Task manager but would not pop up I did fix corrupt files in command prompt from Shift-Restart I was in a reboot loop since June and I finally figured how to fix it. Now I cannot get passed the log in screen I put in my password and it says "Preparing Windows" and it does for maybe 30 seconds to a minute then I see something flash at me then it goes black with a glow. I never updated to the newest Windows 10 I tried but wouldn't let me it wanted me to delete some files before I could update. I tried everything I could I found on the internet I took the battery out and all that and nothing happens always brings me to this black screen.. I am getting irritated with this I tried the "Bring me back to the previous build" but it says I have no previous build so I tried everything I could I have had no help on this forum so I went to this section to get help since it involves the system. If they're is a way to factory reset it or something I tried the command prompt to factory reset but it says "Unable to reset this PC due to corrupt files" something like that.
Someone please help me??
