OS Boot Manager UEFI setting won't save

[anickname028]

I'm having an issue where if I exit the "OS Boot Manager" option it simply resets. Is there a way to, y'know, make it save? (I'm dualbooting Debian 12 and Tiny11, and yes my CMOS battery is fine. I know that by installing Linux or Tiny11 I remove my warranty.)

HOW are you entering this boot manager?  IS this something you are accessing through Linux?

Asking because I multi-boot using Linux distros and differerent OS versions and my preferred Linux boot manager is rEFInd.  You should look that up.  It is easy to install and will show Linux distros and Windows versions in the same graphical screen.

I go into the firmware settings (pause startup, then F10 to edit UEFI settings), System Configuration, boot settings, then OS Boot Manager. I want to use GRUB, but windows forces it. Do I just remove Windows 11? And no, the boot manager is what selects what system to boot. Not a Linux feature.

If you reboot into Linux distro and install rEFInd, that will provide you a graphical boot manager that also has options on the menu to boot directly into the UEFI settings.

I am talking about the UEFI not booting the right bootloader; not needing rEFInd. Although I will check out rEFInd, sounds better than GRUB.

When the PC boots, it runs rEFInd and it does a quick search to find ALL the boot loaders in the PC.  It then builds a graphical menu of what it finds, along with icons that allow you to do other stuff, like boot into the UEFI settings.

So, you don't have to do any text file or script editing to identify the boot loaders -- like you do with GRUB; it simply finds them for you, and builds the menu itself on the fly.

There are also customizing options you can use.

It has become my all-time favorite boot manager.

Found the fix. I was pressing ESC to exit the sub-menu instead of F10. I set it up and now it boots GRUB GUI automatically.
