If the drive is password-protected, we can not assist you with bypassing that, as that is a violation of forums policy.

Also, since that is most likely done in the BIOS, you won't be able to install another OS to bypass that, either.

For BIOS or power-on password resets, read this HP thread: https://support.hp.com/us-en/document/c06368824.

If you are not prepared to spend the money to get HP to replace the motherboard for BIOS password resets, you could take the PC to a local repair facility to see if they can do it for you -- but we are unable to assist in that.
