Hi,

The failure code indicates "Hard Disk 1 Full Test Failure"

You will need to replace the Hard Drive and reinstall the OS.

Here is a small guide:

So what you need is a 2.5" SATA3 hard drive (max 2TB because of the thickness of drive). You can get from your preferred brand such as Seagate, WD...

Example:

https://www.amazon.com/Seagate-Barracuda-2-5-Inch-Internal-ST2000LM015/dp/B01LYNQXCP/ref=sr_1_4?ie=U...

or you could opt for a 2.5" SATA3 SSD which would improve the everyday performance of the PC

Example:

https://www.amazon.com/Samsung-Inch-Internal-MZ-76E1T0B-AM/dp/B0781Z7Y3S/ref=sr_1_1?s=electronics&ie...

On page 36 of the service manual you can see the steps to replace drive:

You will need to reinstall the OS on the drive, either by using recovery disks, migrating a backup image or by downloading media creation tool from Microsoft on different PC running and creating a bootable pendrive with the OS on it on a different computer. (there is an explanation on the Microsoft web page on how to create the pendrive) Windows will automatically activate once installed and connected to the Internet.

If you choose this option you will need to use the pendrive to perform a clean install of Windows 10. You might need to disable fastboot and secure boot in BIOS (probably not). So, insert the pendrive in the PC and it should boot directly from the drive. If not, turn off the PC by holding the power button. Press the power button and immediately keep pressing ESC  until the startup menu appears and then press F9 and choose the pendrive in the boot menu. Once it boots from pendrive follow the procedure to install Windows. You do not need a product key as it is in the firmware.

When finished installing allow Windows to completely update and find all or most drivers. You can follow this process by going into settings > Security and update > click on Verify for updates. You might need to reboot a couple of times. Once completely updated you can go into device manager and see if there are any missing drivers (there will be yellow exclamation mark next to the device). You can find these drivers and software on the HP support page for your product.

 I recommend installing HP support assistant which will help to keep drivers up to date and much more. Here you can download latest version
