I'm assuming you're trying to reset from Update & Security(Recovery/Reset This PC)? If yes, I'd suggest you try from Advanced Startup. Please go back to Update & Security,click on Recovery, and then Advanced Startup( Restart now). Stroll down to Troubleshoot, click on it, and then Reset this PC.

I’m a frequent Dell customer, and I’m also having problems resetting my Mom’s Inspiron 15R 5520.  Ran into slight problems upgrading to Windows 10 via a Windows update in March, but the real problem began today when I tried to disable Mom’s Microsoft Live account because she felt it was annoying.  All things possible then went haywire – on all Admin accounts, the Left-Click Start stopped working, the Taskbar and Task Tray Icons became disabled, Admin user accounts can no longer be managed, and access has been restricted to the C:\drive.  Booted into Safe Mode to do a factory reset.  Went to Troubleshooting > Advanced Options and tried every possible option there is for Reset and Restore.  Each ended with “A Problem was detected”.  No disc was received from Dell at purchase, so I’m unable to do a manual reset, and contacting Dell supported won’t help because I don't believe they can even remote into the laptop.  Tried running Powershell to repair the Start Left-Click, and many command at the CMD prompt seem to be missing, e.g., 'ms-settings'.

Any help or direction you can offer would be greatly appreciated.  This laptop was purchased for my 83 y/o Mom as a birthday present a couple of years ago, and has rarely ever been used (~ 4-5x).  Her heart is broken!

It also a possibility the old windows folder could be causing problems with the Reset option. I'd suggest you check Storage settings for old windows folder and consider removing it. Please click on link below:

I doubt it's option 2 -- The computer came with W-10 as the o/s -- I had to upgrade my old laptop from W-8.1 to W-10, but not this one. I'm going to try Suggestion 1 later tonight just before I shut down for the night. Hopefully it'll work and fix the underlying issue leading to the need for a reset. I'll post an update when the process finishes playing out.

Nothing works. I discovered a fix though -- get rid of Windows in favor of Linux, or cut your losses and buy a Mac. Windows owns your PC, not you.

I'm sorry the suggestions didn't help....:emotion-6:

I have one more suggestion, download Dell Windows Recovery Image from the link below. Hopefully it will help. Good luck.

By the way, please list Dell model number for Dell reps and others to see and perhaps help resolve your problem. Example: Dell Inspiron 3543

Just one question before I go this route (and BTW, thank you for being so willing to help -- it is appreciated even if I occasionally seem testy): does this wipe all of my files (i.e. music, photos, videos, Word docs, etc) from the hard drive? Or is it the reset that preserves personal data?
