From your photos, it looks like the Long DST check never finished -- and that most likely indicates that the hard drive has died, as you have already run the diagnostics and they won't complete.

All-in-Ones are basically oversized laptops because like them, it is real hard to get the case open without breaking it and we have no instructions that I know of that we can provide.

You need to see if there is any place local that will open it for you so the drive can be replaced.

Once you have the new drive in place, read the instructions below about using the HP Cloud Recovery...

If your PC is a 2016 model or newer, you should see if you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC.

The recovery drive can then be used to install Win10 and the HP drivers and utilities that originally came with your PC.
