A HP ProBook G5, users do not remember what has been done in the BIOS, now want to go in to change the settings, but the power on either ESC, F1-F12 are useless, the machine will go directly to the WINDOWS10 operating system, hit HP 400 phone, no solution. I have not encountered this situation before, but notice that after the boot directly out of the hp+ circle interface, I remember there should be a separate HP icon interface flash a bit, but no, think possible bios set up after boot skip setting the BIOS interface directly into Windows option. So Google found an article on HP: https://support.hp.com/us-en/document/c05381067 (Note this article does not look at other language versions, other language commands are wrong)
The article mentions that "after performing a system restore, the computer cannot use the F10 hotkey to enter the BIOS setup." After the image is restored, press the F10 hotkey and the computer skips the BIOS settings and loads Windows directly. After you perform a system Restore, the issue occurs when you enable fast boot in the BIOS . "It's the same as I thought. The page also provides a workaround:
Note the correct command line is:biosconfigutility64.exe/setvalue: "Fast Boot", "Disable"
No more spaces, no fewer spaces

Restart F10 resume normal after running, enter BIOS
