Fedora HowTos

Set default grub boot entry in Fedora

The following instructions show howto setup default boot item in grub menu unser Fedora Linux. This may be handful in case of dual-boot setup when the default item must be set to another OS.

Method 1. Specifying boot item by name

This method commands should be launched again after installing new kernel during updates (as it re-launches grub2-mkconfig).

Check boot items in grub.cfg:

# awk -F\' '$1=="menuentry " {print $2}' /boot/grub2/grub.cfg

This may produce output like the following:

Windows Boot Manager (on /dev/sda2)
UEFI Firmware Settings

Set default item by its name:

grub2-set-default "Windows Boot Manager (on /dev/sda2)"

Method 2. SPecifying boot item number

This method will set N-th item in a boot list and i is assumed that item order does not change during updates. One won't need to re-run this method installing new kernel.

Open grub config file /etc/default/grub in any suitable text editor and adjust the parameter GRUB_DEFAULT to the value of new default boot item starting with 0.

# nano /etc/default/grub

GRUB_DEFAULT=4

Run grub mkconfig to apply new grub configuration:

# grub2-mkconfig -o /boot/grub2/grub.cfg
