I have used many laptops from HP. And I have no experience to require Windows to enter UEFI firmware/BIOS settings. User guide of HP Pavilion - 15-au123cl has common description as follows: > Turn on or restart the computer, quickly press esc, and then press f10. You can download the user guide from here: https://support.hp.com/us-en/product/setup-user-guides/hp-pavilion-15-au100-notebook-pc/model/12780759 And if you want to run Windows without wiping NetBSD, Windows To Go USB stick is useful. You can easily use Windows To Go USB stick with Rufus for Windows. https://rufus.ie/en/ Sadly it requires a working Windows environment.
