Persistent grub menu

[oren]

Since the last update (circa June 8) grub menu re-appeared, although the settings in etc/default/grub have not changed and are as follows:
GRUB_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT_STYLE=hidden

system info:
Manjaro X86_64
Kernel 5.10.41
KDE Plasma 5.21.5

Any ideas?

Have you tried what is described here:

How to hide GRUB menu ? when

For lack of proper solution, I used this solution from the archived forum. So in the /etc/grub.d/30_os-prober file I changed this line of code adjust_timeout () { if [ "$quick_boot" = 1 ] && [ "x${found_other_os}" != "x" ]; then cat << EOF set timeout_style=hidden # was timeout_style=menu if [ "\${timeout}" = 0 ]; then set timeout=10 fi EOF And it works, but I don’t know how it will behave if trying this with dual boot. So for anyone that tries this, its at your own risk.

Thanks for pointing this out to me.
it seems that the problem is elsewhere -
Although os-prober disable is set to true, it still probes and finds Windows bootloader (long since deleted)
GRUB_DISABLE_OS_PROBER=“true”
so even if I use efibootmgr to delete the Windows boot menu entry, it reappears.
Hence the undesired grub menu.
Now I am looking for a way to get rid of the pesky os-prober, delete the Windows boot entry and hopefully grub menu will stop showing up

EFI boot entries (efibootmgr) and grub are 2 unrelated things - one does not influence the other.

Check if multiple GRUB_DISABLE_OS_PROBER-lines are in your config:

$ grep GRUB_DISABLE_OS_PROBER /etc/default/grub

and post output of

$ sudo update-grub

Thanks for your reply.
You were spot on! I had multiple entries.
This is the new output of sudo update-grub:
[oren@oren ~]$ sudo update-grub
