= Adding other operating systems to the *GRUB2* menu
|

|

Normally, *GRUB2* is preset to boot multiple operating systems during the Fedora installation process. If you can, it is advisable to install non-Linux operating systems first. Then, during the installation process, all those operating systems and their locations will be discovered and properly set.
|
||
|
|
|
||
|
|
Sometimes, however, you cannot use this approach and you will have to create the bootloader configuration file again to enable it to boot more operating systems.
|
||
|
|
|
||
|
|
.Before you start
|
||
|
|
|
||
|
|
* Make sure that the operating systems are on disks, connected to the system.
|
||
|
|
* You have the `os-prober` package installed.
|
||
|
|
|
||
|
|
.Procedure
|
||
|
|
|
||
|
|
. Install *GRUB2* into the MBR of your primary hard disk.
|
||

. Recreate the *GRUB2* configuration file.
|

|
||
|
|
----
|
||
|
|
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
|
||
|
|
----
|
||
|
|
|
||
|
|
.More information
|
||
|
|
* The `grub2-mkconfig` command will add entries for all operating systems it can find.
|
||
|
|
* When problems appear, see the link:http://www.gnu.org/software/grub/manual/grub.html#Multi_002dboot-manual-config[GRUB manual] to solve issues with booting secondary operating systems.
