Greetings @vsnelsonjr, 

Welcome to HP Forums and Thanks for the post. 

I understand that you are unable to reformat your computer. Don't worry, I will be glad to help you.

However for me to be able to assist you better, I request to provide the requested information.

Are you able to boot the computer to the desktop?

Are you using a wireless keyboard?

Have you changed the operating system on your computer?

Have you deleted the recovery partition?

If you are able to boot the computer to the desktop, click on the Windows button.

In the search box, type recovery manager. 

In the recovery manager, click on the system recovery option and follow the on-screen instructions. Refer to this HP article for assistance. 

An alternate method to enter recovery manager is by tapping F11 on startup to enter recovery manager directly or by tapping ESC on startup to enter the Startup Menu and then select F11 or recovery manager. Please use an USB keyboard connected to the rear of the desktop if possible.

If this fails, you would need to use the recovery kit created on your computer. If you do not have a recovery kit, please contact our phone support for the shipping options. You can also refer to this article for assistance.

Let me know if this helped.
