Recently, I was planning on selling my laptop, so I wanted to reset it. I started up my computer and hit the escape key and then there was a menu called, "Startup Menu" so then I hit the F11 key which brought up the System Recovery screen. I then chose the option to troubleshoot, then reset this pc, then I wanted to Remove Everything. Everthing seemed to be working and then around 46% I got the message, "There was a problem resetting your PC" so I had to cancel it. I then tried to startup my PC, and my lock screen background was gone, I signed in and it said it was preparing Windows. When it finally finished preparing windows it was just a black screen. There was no desktop, or taskbar. I was able to open task manager and open File explorer, but when I went into there most of my programs had been deleted. I hadn't backed up my computer before doing this, as I was going to sell it and I had no use for a backup. I waited on the black screen after signing in one time and the desktop and tasktbar appeared. But, I wasn't able to click on the Windows Start Menu. Or search windows through the Cortana thing. I don't know what to do.
