I need to know how to change the Grub menu entry labels. I have Win 10, Manjaro KDE and I will be installing another version of Manjaro (haven’t decided yet). I would like it to change the labels to say:
Win 10 Pro
If there is some documentation I should read please include that as well. I’m still learning linux and manjaro. Thanks.
In my opinion, the best way to do this is to edit the scripts in
/etc/grub.d/. If you edit the
30_os-prober script, you can change how the detected operating systems from
os-prober are displayed;
10_linux is the script that you can edit to change the display name for the operating system that you are using GRUB from. Alternatively, you can use the
40_custom script to write custom entries.
This will require some knowledge of shell scripting, but these scripts will then continue to correctly create your desired entries after kernel updates. Always backup before doing this type of editing, and do not edit all the files at once (i.e. make sure you haven’t made any mistakes before moving on to the next one).
I don’t understand how the scripts work in order to change the menu labels.
we can change /etc/lsb-release, key
DISTRIB_DESCRIPTION, os-prober use this key
In my second manjaro, i use a pacman hook for next update
Operation = Install
Operation = Upgrade
Type = File
Target = etc/lsb-release
Description = lsb-release change grub description
When = PostTransaction
Exec = /usr/bin/sed -i 's/^DISTRIB_DESCRIPTION.*/DISTRIB_DESCRIPTION="Manjaro Cinnamon"/' /etc/lsb-release
Does the /etc/lsb-release file get changed with system updates/upgrades and/or switching of the kernel? Also, the “/etc/pacman.d/hooks/” folder does not exist. I’m on Manjaro KDE 22.0.0.
It’s at us to create this
/etc/pacman.d/hooks/” directory (and file)
This hook change
/etc/lsb-release content only when this file is updated by pacman
OK so I did a 2nd install of Manjaro KDE (I’ll change it do a different Manjaro edition later) and upgraded it to 22.0.0 and installed the 5.19.17 kernel on both installs.
In the first Manjaro install I updated the /etc/lsb-release file to have:
DISTRIB_DESCRIPTION="KDE 1 Manjaro Linux" as the value for the
The 2nd install has:
DISTRIB_DESCRIPTION="KDE 2 Manjaro Linux"
I added the appropriate hooks content as specified above by @papajoke that matches the quoted text strings above. I logged into the 2nd install (KDE 2), and ran:
sudo grub-mkconfig -o /boot/grub/grub.cfg
When I reboot I get:
- Manjaro Linux
- KDE 1 Manjaro Linux (22.0.0) on …
- Windows boot loader
It is strange that the grub-mkconfig picks up the changes in the 1st install (KDE 1), but not the changes in the 2nd install (KDE 2). Is there something I missed?
lsb_release is only for os-prober
for default linux (grub owner), entry (prefix) is in etc/default/grub , key :
so, for you:
GRUB_DISTRIBUTOR="KDE 2 Manjaro"
if I made the appropriate change to the /etc/default/grub in each Manjaro install, as well as the changes to /etc/lsb-release in each Manjaro, and create the appropriate pacman hooks, then can I run grub-mkconfig or update-grub in either Manjaro install and still get the desired result?
I did the above and it worked. I haven’t tested after upgrading to a newer version of Manjaro since I’m already on the latest version.
The solution to editing grub menu labels is contained in the posts in this thread by @papajoke.
