Thank you for posting on HP Support Community.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
- What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824 (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
- What is the operating system?
- What is the exact issue with the hardware diagnostics UEFI tool?
Keep me posted for further assistance.
