Boot the problem PC to that USB media from Microsoft and once the screen loads you can reinstall Windows from that media.

Hey so I did what you said and it took me to the download screen but then it gives me two chooses to either upgrade: install windows and keep files, settings, and applications or custom: install windows only (advanced) and I don’t know which to choose

[TheOldMan]

Well, it depends on if you wish to keep the software and apps that were installed before.  The custom will ask if you wish to clean out and start over, which I would do as a last resort.  If you were satisfied with the way it worked before the problems then try the first method.  If that fails to give you satisfaction, you can go back and do it again and pick the custom install, wipe out the drive and let Windows do what is called a "Clean Install", which will be totally new and fresh install.

Here is a different guide

Start the custom install.  When you get to this screen

 you could delete them all and tell Windows 10 to install itself in the unallocated space.
