GRUB2 GUI?
- Vous devez vous identifier ou créer un compte pour écrire des commentaires
Is there a GUI utility somewhere that will help me edit my GRUB2 entries? I dare not edit the files in /etc/grub.d ;).
There are several.
Grub-customizer is popular

Additional tools listed on the arch wiki page

Notice that the most common things you want to change are not in
/etc/grub.d/*. They are in /etc/default/grub. This file, whose content is
commented, is pretty easy to change. It simply is a list of Shell of
variables to instantiate. As for listing the installed operating systems,
'sudo update-grub' does a good job (at least it has always worked for me)...
and it does not write in /etc/grub.d/* either. It writes in
/boot/grub/grub.cfg.
And remember to have a livecd or liveusb at hand in case you happen to break
your boot. It happens every now and then to me but isn't hard to fix as long
as you have something that boots.
grub-customizer totally did the trick, excellent!
lembas, do you have a simple procedure (or a link to such information) for restoring grub from a livecd or liveusb? Thanks.
The process is relatively straight forward. It's not really restoring grub, just fixing its configuration.
In case of trouble you must first boot a live media and then mount the harddisk and proceed to directly edit /boot/grub/grub.cfg (on the harddisk, naturally, instead of on the live media). Just undo the changes that caused the problem. You could make a backup copy of the file when it still works for reference.
