Dual booting automatically selecting the windows for booting by default

Its my first post here
i am the using the endavour os with the i3wm for past few months(no dualboot)
but recently i dualbooted my system and i had a issue:–

everytime i start my laptop it automatically boot to windows,
i can boot to endavour os by using the boot menu but i want my laptop to automatically boot to the endavour os

i just need the EndavourOs grub menu to see first
whenever i stary my system!! it will solve my problem

there was a thing in acer boot menu that you can set priority for the os to boot but its just showing a number “2” there :frowning:

i just want to see this menu first thing after i start my system

Thank you guyz in advance!!!

Try using efibootmgr to change the boot order. You can view the current boot order like so:


Examine the boot order, then decide what order you want it to be in and set it with the -o flag.

efibootmgr -o 1,2,3,4

Change “1,2,3,4” for your desired boot order.

sudo may be required for that one, I can’t remember.

If the Linux boot variable is missing for some reason you can generate a new one with efibootmgr -c. You can see more options and usage examples in the man page: https://man.archlinux.org/man/efibootmgr.8

I hope that helps, welcome to the community @Kaeyaaa. :wave:

i’ve tried this but it still hasn’t resolved my problem

sudo efibootmgr -o 0001,0003,2001,2002,2003

i’ve used this command to change the boot order, but after rebooting its reverting all the changes.
