Hello Guys,
In this article, we will be comparing GRUB and GRUB2 boot loaders.
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. If you do not dual boot, you may not have seen this window.
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.
BONUS!!!
BURG
As for BURG - the capitalization seems to depends on who you ask - it is a fork of GRUB. The main reason most users consider BURG is for the theming possibilities, replacing the two color boot screen above, with a colorful interface.
