[Solved] Help with grub

[ZiusCr]

SOLVED: Turns out it was because I was using BTRFS in my drive, using ext4 it works just fine.

I have dual boot debian and windows 11, just for gaming, on a laptop. My laptop is usually closed and I use an external monitor, and I used to change from debian to windows using

Code: Select all

sudo grub-reboot 2 && sudo reboot

, and then back to debian from windows simply restarting, but now it always uses windows by default, the third option. ¿How can I make it pick the first option always? I've tried edited /etc/default/grub, and then run

Code: Select all

update-grub

, but it appears to do nothing and still go to the third option.

My /etc/default/grub file is this:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DEFAULT="0"
GRUB_TIMEOUT="2"
GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# If your computer has multiple operating systems installed, then you
# probably want to run os-prober. However, if your computer is a host
# for guest OSes installed via LVM or raw disk devices, running
# os-prober can cause damage to those guest OSes as it mounts
# filesystems to look for things.
GRUB_DISABLE_OS_PROBER="false"

Did you try to disable "fast boot", either from BIOS or Windows?

Thanks for your help. That didn't do anything, but switching my drive from BTRFS to ext4 solved the problem.
