This is why you should never do that ...

They trashed your laptop and a particular problem with that model is that the "disk drive" is soldered to the motherboard and not replaceable.  So a simple matter of swapping in a new drive is not possible.

You also can not do a built-in reset because the "disk drive" has insufficient room for the work files, so that is not an option.

What MIGHT work is a complete reset using HP Recovery Media that you have to download using another PC, but that will wipe out our ENTIRE drive in the process.

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.
