Welcome to the HP Support Community. I'd be happy to assist you with the recovery.
To better assist you - May I have the exact model name of the product? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.
While you respond to that, if the computer has the recovery partition, try these steps -
1. Shutdown the computer.
2. Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.
3. Press F11 once for System Recovery.
4. Choose the Keyboard Layout.
5. Click on Troubleshoot.
6. Go to Recovery Manager and click on System Recovery.
Note : Back-up all your data as System Recovery will delete everything that you had saved or installed on the computer.
Hope this helps! Keep me posted.
