= 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.

Adding other records into the *GRUB2* menu only means to run `grub2-mkconfig` command to regenerate the configuration files. During this process, all operating systems known to the system will be added into the configuration. By reinstalling *GRUB2* into the MBR, this configuration will be used for further boots.

.Before you start

* Make sure that the operating systems are on disks, connected to the system.
* You have the `os-prober` package installed.

.Procedure

. Recreate the *GRUB2* configuration file.
+
----
# grub2-mkconfig -o /boot/grub2/grub.cfg
----

. Install *GRUB2* into the MBR of your primary hard disk.
+
----
# grub2-install /dev/sda
----

.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.
