Can UEFI firmware compel the operating system to alter its boot mode?

Because Windows 8 and 10 launches with Hiberboot enabled by default, when you go to Start->Power->Shutdown, the machine really goes into S4, not S5. I need to be able to compel Windows to conduct a full boot rather than "wake" from S4, regardless of how it was previously shut down. I tried forcing my UEFI BIOS BootMode to always be BOOT WITH FULL CONFIGURATION, but it didn't work - Windows still uses the quick boot route. I read this article to understand it more correctly but I need more information.

It used to be able to set the DIAG mode with the Simple Boot Flag in the BIOS; this may still work for me, but it does not appear to be supported in Windows 8/10. Is there a UEFI variable or another way to communicate with the OS to boot in full or diagnostic mode?

You're not explaining the reason why. (or maybe I am the one missing the point...)

Tha said, please have a look at the whole 1.5 Paragraph: https://wiki.archlinux.org/title/Dual_b … ibernation

That topic doesn't seem to deal with uefi booting, but the older bios booting .
I never heard of "bootmode BOOT WITH FULL CONFIGURATION" , can you elaborate ?

You may be able to use windows Boot Configuration Data to force something, https://learn.microsoft.com/en-us/windo … in-windows gives an overview of those.


Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
