i installed fedora alongside manjaro kde and now fedora grub menu is popping up during boot i want to disable that.
i previously had turned of grub menu in manjaro by setting
GRUB_TIMEOUT=0.0
GRUB_HIDDEN_TIMEOUT=0.0
i tried changing these settings back to
GRUB_TIMEOUT=5
but it had no change
of course i did sudo update-grub
what i want to achieve
1.grub menu should not pop up during boot manjaro kde should be booted
2.i should be able to make the manjaro boot menu work by changing the /etc/deafult/grub so that i can boot fedora when i need
There is too many factors to consider - and any deviation from your actual configuration will not be helpful. As example - Fedora usually installs using LVM - so if this is the case - anyone here telling you what to do could potentially cause your Fedora to fail - and no one here wants provide you with copy-paste examples which may cause more problems.
Now that I have properly warned you - the basics for installing the grub boot to a BIOS system is as follows - replace /dev/sdX with the actual primary boot device path and execute as root (e.g. using su or sudo)
Manjaro grub can boot other distros but other distros have difficulty booting Manjaro @linux-aarhus is far far more knowledgeable than me so is better placed to help.
But what I’ve done in the past after installing another distro (mint) alongside manjaro is use a live manjaro USB and then chroot to install/update grub to manjaro.
