Using GNU GRUB 2 in Fedora
GRUB 2 provides various feature enhancements over the previous GRUB version
(referred to as "GRUB", or "GRUB Legacy") which has been unmaintained upstream
for years. GRUB has thus been deprecated in Fedora and replaced by GRUB 2 for
BIOS systems. (EFI systems still uses GRUB Legacy from the new grub-efi package.)
The GRUB 2 utilities are prefixed with 'grub2':
The default location for boot loader installation is /boot/grub2/ .
GRUB 2 in Fedora
The Fedora installer (anaconda) will make sure grub2 is installed for new and
updated systems. It will run grub2-install to install the boot loader in the
MBR and in /boot/grub2/, and it will write /etc/default/grub and run
grub2-mkconfig to create /boot/grub2/grub.cfg.
The active boot loader will not be changed when the GRUB 2 package is updated.
A new boot loader can be installed with something like:
grubby will patch grub.cfg (through /etc/grub2.cfg) when new kernels are
installed. The GRUB 2 configuration system in /etc/default/grub and /etc/grub.d/
is thus only used initially by anaconda, but it is possible to generate a new
grub2-mkconfig -o /boot/grub2/grub.cfg
The GRUB 2 manual can be found in grub.html or on
