I bought this ProBook 6570b second hand for personal use, cannot boot from any drive except the laptop hard drive; I wanna upgrade to Windows 8.1/10 but cant do so as the bios has an unknown administrator password and boot sequence cannot be changed. Tried chatting with hp support but they just keep redirecting from one Tech guy to another and the issue is still unresloved. Kindly help me with this.

Outside of the tool by Mazzif or changing chip- no one here can help you other than official HP Tech Support. They should provide you with a .bin fie to clear/reset password.
