Hi @CalicoFlint

Welcome to the HP Support forum. Thank you for posting.

It's good you want to follow best security practises and reset the device operating system.

Because the standard means failed (due to faulty/corrupted recovery partition , for example), here is what you can do

- You can directly download Windows 10 ISO from MS site or download >> Media creation tool from Microsoft site, create installation DVD or installation USB  and  proceed with clean installation/reinstallation.

Download:

>> https://www.microsoft.com/en-us/software-download/windows10ISO

Make sure you select the proper version (32 or 64 bit / Home or Pro) 

Media Creation tool will always provide you with the latest Windows version/build - now 1709 Fall Creators Update.

- When download completes, you will need to write  the ISO image and boot from a bootable media. You will need a blank USB pendrive (min 4 GB capacity)

When ready with the USB drive or with the DVD:

Please, shutdown the computer using the power button.

Insert the Windows USB thumdrive prepared previously

Power on the PC.

As soon as you press the power-on button, start hitting the Esc button repeatedly (like tap-tap-tap).

This should open a HP Startup Menu

Choose F9 to open Boot options. Select the USB thumb drive as a boot option.

- Follow the on-screen instructions to install Windows 10. Perform clean installation/custom installation (not repair).

Delete all existing partitions and install Windows on Disc 0 Unallocated space

- After successful Windows installation, install drivers taken from HP web site or via Windows Update/Device Manager >> http://support.hp.com/us-en/document/c03330139

- Make sure Windows is Activated by going to Start > Settings > Update & Security > Windows Activation

- You may wish to stop some of the Windows Telemetry by using free tools such as Spybot AntiBeacon or DWS Lite

Hope this helps. Let me know how it goes
