Difference between GRUB and GRUB2

[linux-user]

Hey,

Could anyone help me to understand what's the difference between GRUB and GRUB2?

Thanks in advance

GRUB

The "GRand Unified Bootloader" is the software that is loaded by your computer after it turns on (after your computer's BIOS loading screens). GRUB then either automatically boots Ubuntu or gives you a list of installed Operating Systems and lets you choose one to boot (people not dual booting will probably not see the GRUB interface).

GRUB 2

A complete rewrite of the original GRUB (legacy GRUB). On the surface the majority of users won't notice any difference but the new version has fairly major structural changes and should be more reliable. 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.

Since 9.10 Ubuntu has used GRUB 2 as the default boot loader for clean installs (prior to this it was GRUB).

BURG:

Burg is a brand-new boot loader based on GRUB. It uses a new object format which allows it to be built in a wider range of OS, including Linux/Windows/OSX/FreeBSD, etc. It also has a highly configurable menu system which works in both text and graphic mode. Additional features like stream support and multiple input/output device are also planned.
