Hello.
I have EndavourOS on NvMe and Windows 10 on other SSD. All works. I can boot to both systems. But No matter what I try it won’t remember last choice in grub. It always boot up to first choice that is EndavourOS.
Here is my /etc/default/grub after I changed it I ran sudo grub-mkconfig -o /boot/grub/grub.cfg
Tried multiple versions with multiple quotings etc. nothnig seems to have effect
# GRUB boot loader configuration

Basically it’s allways same answers even on Arch forums and it looks like it doesn’t works for me. Any help and idea would be appreciated. Thanks.
Didn’t helped. Tried that now again Ran sudo grub-mkconfig -o /boot/grub/grub.cfg after changes
Hello, thank you
I’ve red about that somewhere but no. I have ext4. Screenshot for proof. Other disks are NTFS. I just let installer do it’s magic. Didn’t changed anything. That’s why I’m confused what could be the problem
Yep that’s why I’m writing here. Can’t figure it out with google.
I’ve choosen grub during instalation because that was one I was sort of familiar with.

Yes it is there as last option under “UEFI config something” and I can boot into it without problems. But when I restart or shutdown form windows. Next boot will goes to Endavour because pointer (highlighted line) is on EndavourOS
I’m not so sure that you’re looking at a grub menu.
Your grub file, as posted in the first post, shows this:
# Probing for other operating systems is disabled for security reasons. Read
# documentation on GRUB_DISABLE_OS_PROBER, if still want to enable this
# functionality install os-prober and uncomment to detect and include other
# operating systems.
#GRUB_DISABLE_OS_PROBER="false"
That shows os-prober as being disabled, so grub will not find or display any other operating system.
