Hi British.Army
I am Dave, I will help you with this.
If that reset operation is constantly failing, then, your recovery image may be corrupt, the best option is to backup your personal files, then clean install Windows 10 from a bootable USB, that will also create a new recovery image.
You can reinstall Windows 10 at any time and it will not cost you anything !

to download the Media Creation Tool (Click on Download Tool Now), with that you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), you can create a bootable USB flash drive (min 8GB) using that tool
Then, Boot your PC from the Installation Media you just created (change Boot Order in your BIOS) to begin installing Windows 10
Since you previously had Windows 10 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC', and activation will not be an issue, your PC will have a digital entitlement stored on the Microsoft Activation Servers
