so with this method, same thing happened like last time. After I restarted and selected my boot entry, the next restart, it does choose my saved boot entry, which is First entry > Second sub-entry,
I restarted it couple of times and it works just fine.
But the next day, just like my first solution, it will choose First entry > First sub-entry, which does not boot properly anymore.
(Actually, I don’t know which sub-entry it chosen. But it’s definitely not booting properly. Only the second sub-entry, the one with initramfs that worked)
I wonder if this is a bug?
I probably should have posted my
/etc/default/grub, my bad.
But I admit, I didn’t set
GRUB_CMDLINE_LINUX_DEFAULT exactly like the example. I keep the default since it already had
udev.log_priority=3. I wonder if that’s what causing it?
I will remove the
splash apparmor=1 security=apparmor,
sudo update-grub, then set my default again. If tomorrow it still works properly, I will mark this as solved.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor udev.log_priority=3"
