Most of the Linux distributions that we use today, have the GRand Unified Boot-loader as their default boot-loader. Recently the developers of GRUB (GNU) have released the latest version GRUB 2 which have lots of improvements compared to its previous version. By default Ubuntu 9.04 comes with the old GRUBbootloader, so today we are going to see how to install the new GRUB 2 on our favourite Ubuntu 9.04!

First lets see what are the features of GRUB 2 :

• Scripting support, such as conditionals, loops, variables and functions.
• Graphical interface.
• Dynamic loading of modules in order to extend itself at the run time rather than at the build time.
• Portability for various architectures.
• Internationalization. This includes support for non-ASCII character code, message catalogs like gettext, fonts, graphics console, and so on.
• Real memory management, to make GNU GRUB more extensible.
• Modular, hierarchical, object-oriented framework for file systems, files, devices, drives, terminals, commands, partition tables and OS loaders.
• Cross-platform installation which allows for installing GRUB from a different architecture.
• Rescue mode saves unbootable cases. Stage 1.5 was eliminated.
• Fix design mistakes in GRUB Legacy, which could not be solved for backward-compatibility, such as the way of numbering partitions.

Now lets see how to install it on your system :

1) Open the terminal (In the main menu Applications > Accessories > Terminal) and type sudo apt-get install grub-pc (give the password when prompted)
