My HP Spectre x360 boots really fast and I can’t figure out how to access the BIOS screen?
You should hit Esc + F10 at the start of the boot sequence.
On HP Spectre X360 15-bl012dx (2017 15-inch):
esc during boot. A menu appears. Press
F10 to enter BIOS setup.
You have to hit
F9 during bootup. If you miss the right point, shut your laptop off, begin pressing the
F9 key continously and then start your laptop. You can’t miss it that way.
Pressing F9 multiple times really fast at start up will get you to a boot menu, (Just holding down the F9 key won’t work) once in that boot menu press F10 and that will get you to the main BIOS screen.
