Problem scenario
You turn on an HP computer (e.g., a desktop or laptop) and press Esc to go to the Startup Menu. You then press F10 or use the down key and press enter to get to the BIOS menu. When you are there you see the option you need "Update BIOS Using Local Media" is grayed out. You entered administrator-level credentials successfully. You have not other credentials to log into this HP startup menu. What do you do to update the BIOS?
Solution
Log in as a guest user. For some reason a guest user may be able to have see clickable blue text "Update BIOS Using Local Media." This solution can work.
