Upgrade to GRUB2
By on October 29th, 2009

Grub or the Grand Unified Boot Loader is a popular boot loader for Linux. A few months back, Grub was upgraded to Grub2. Grub2 has been reprogrammed from scratch, giving it better modularity.



Grub2 has the following goals:

  • Grub2 has added scripting support for use of loops, variables and functions.
  • Targets a better graphical user interface and dynamic loading of modules at run-time which extends the usage of the boot-loader.
  • With Grub2, we have better portability options across various platforms giving it a wider user base.
  • Grub2 has also added support for non-ascii characters.
  • Object oriented framework for devices, drives, files, file systems etc.
  • Enhanced rescue mode.
  • Cross platform installation.

All these features packed into grub2 gives it a fresh new feel.

Grub2 is available by default in the final build of Ubuntu Karmic Koala. For those looking to upgrade to grub2, follow the tutorial here.
