[[setting-default-entry]]
|

|
|
== Setting default entry
|
||
|
|
|
||
|
|
Due to `grub2-mkconfig` (and *os-prober*) we cannot predict the order of
|
||
|
|
the entries in `/boot/grub2/grub.cfg`, so we set the default by
|
||
|
|
name/title instead.
|
||
|
|
|
||
|
|
.Before you start
|
||
|
|
|
||
|
|
. Open `/etc/default/grub` and make sure these lines exist in the file.

GRUB_DEFAULT=saved
|
||
|
|
GRUB_SAVEDEFAULT=false
|
||
|
|
----
|
||
|
|
|
||
|
|
. Apply the changes to `grub.cfg` by running.

$sudo grub2-mkconfig -o /boot/grub2/grub.cfg

$sudo grub2-set-default "<submenu title><menu entry title>"

.More information
|

|
|
If you understand the risks involved, you can manually modify the
|
||
|
|
`/boot/grub2/grub.cfg` file. In that case, set the number of the default operating system using the `set default` variable.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
----
|
||
|
|
set default="5"
