Background

GRUB is a popular boot manager for people with many different operating systems installed on one machine or hard disk. FreeLoader is ReactOSs bootloader and also a possible boot manager. If you have GRUB already installed and then install ReactOS, FreeLoaders multiboot abilites become redundant and annoying. This document shows how to keep FreeLoader from doing much but acting as a bootloader for ReactOS.

Method

FreeLoader can be loaded as a "multiboot kernel" by multiboot compliant bootstrap loaders like GRUB. To load FreeLoader from GRUB use something like this:

title ReactOS
	root (hd0,0)
	kernel /freeldr.sys

You can also override settings in the [FREELOADER] section of freeldr.ini by passing them on the command like, like this:

title ReactOS
	root (hd0,0)
	kernel /freeldr.sys DefaultOS=ReactOS TimeOut=0

title ReactOS (Debug)
	root (hd0,0)
	kernel /freeldr.sys DefaultOS=ReactOS_Debug TimeOut=0

After selecting "ReactOS" from the GRUB menu you won't have to make another selection on the freeldr menu because of the "TimeOut=0"
