I wish we could help you, but sorry, due to recent changes in Community policy, we are no longer able to provide any assistance with password reset or recovery issues.
Also please note that now, to resolve a forgotten BIOS password issue, a system board replacement is required -- and additional customer costs apply, HP has issued this post about BIOS passwords: https://support.hp.com/us-en/document/c06368824.
4d. No posts shall include instructions or directions intended to bypass or subvert security measures, including passwords, locking mechanisms, fingerprint scans, etc., or to bypass any safety measures.
For assistance NOW, you have to contact your regional HP Customer Support location directly as they will confirm ownership of the PC before providing any assistance -- something we are not able to do from here.
