Once a reset fails, running it over and over will not work again.

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.

You will need a working PC and a 8GB USB stick to hold the recovery files.
