Welcome to Grub4dos guide Version 1.4 (17th May 2009). The online version of this guide is available here - any new versions will be posted on this site.
Grub4dos it is a versatile bootloader capable of dual/multi-booting DOS, Windows, Linux and other operating systems. It can be used to select which operating system to load when multiple operating systems are available. It can also be used to (chain)load an operating system when the existing bootloader or partition boot sector has become corrupted - however this will depend on the operating system you are booting.
This guide is aimed primarily at Windows users, but is also relevant to Linux users. All screenshots and commands are taken from Grub4dos version 0.4.4 Final (build 2009-03-31) - unless otherwise stated.
