=== Update GRUB bootloader on BIOS systems
Systems with the BIOS firmware have the GRUB RPM packages updated. However, the installed or embedded bootloader is never updated automatically. It is a good idea to update it between Fedora release versions.
[WARNING]
====
This only applies to BIOS-based systems, *not UEFI-based*. To discover what firmware your machine uses, run the following command:
[source,bash]

$ [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
----
The output returns only UEFI or BIOS, depending on the firmware your machine runs.
