What is the difference between Grub-Leagacy & GRUB-2?

There are some notable differences between the previous Grub-Leagacy and the new GRUB-2.

• Previously in Grub-Legacy partition number's of a hard disk, used to start from 0,1,2,..etc. But in GRUB-2 it starts the partition naming convention from 1,2,3..etc.
• It now recognizes many more new file system's like ext-4
• There are no more stages like stage-1,stage-1.5 etc, in grub image files, like the Grub-Legacy
• Grub-2 has started using modules which can be loaded as per requirement.
• GRUB-2 is capable enough to determine a hard disk partition using UUID's(Universally Unique Identifier)
• The configuration file name is grub.cfg(no more menu.lst & grub.config)
• The new grub-2 configuration file is highly configurable, compared to grub-legacy config file.
• GRUB-2 also supports EFI(Extensible Firmware Interface)
