I have a new G2 800. A recent HP advisory bulletin recommended a critical ME Firmware update and then a BIOS update to the current N01 version 02.17, 11/1/2016. I was able to successfully run both of those updates. However, I am unable to get into the BIOS now at bootup. I have tried repeatedley pressing the following keys (individually) during restart/powering on the desktop with no luck: Del, Esc, F1, F2, and F10. Please advise.
