I'm pretty sure this is exactly what is happening in real life. I pressed F12 damnit! Go into the bios already!!

Some friendly tips from post-silicon validation:

sudo systemctl reboot --firmware

shutdown /r /t 0 /fw

These reboot directly into BIOS.

For Windows CMD+R menu, run it by pressing CTRL+SHIFT+Enter (elevates to admin). You may have to do it twice for some unknown reasons after reinstalling the OS.
