“The first new feature you may (or may not) notice is that
Fedora finally uses GRUB 2 as the bootloader. While one might think
that GRUB 2 was already in widespread use before this change, you
perhaps don’t realize that GRUB 2, for the most part, was only
implemented in any Debian-based distributions. Go outside of the
Debian world and it’s a whole different story.
However, considering that GRUB 2 is actually close to a stable
release, the people over at Fedora decided it was time to get back
to the upstream standard. GRUB 2 brings with it loads of
improvements, more options, and overall better booting.
