GRUB2 banyak menawarkan kelebihan dari pendahulunya, diantaranya adalah

"The new version stores its configuration files differently, which means most online tutorials involving GRUB had to be rewritten. Other new features include the ability to boot LiveCD ISOs from the hard drive; support for other architectures such as PowerPC; theming and other graphical capabilities and scripting support".

Upgrade ini dapat dilakukan melalui perintah berikut.

$ sudo apt-fast update
