How to configure Grub with TRIPLE OS?

He everyone, I have a difficult time in configuring three OS in my boot loader, I have a single HD, and I have XP, Fedora, and SUSE, my boot loader is grub.

How will i configure grub so that the three OS will be present in the boot loader, and that I can run either of the three of my OS?

Your help is higly appreciated.

I have 4 OSs in my HD! Ubuntu, Mandrake, DSL, & ...
It's simply by configuring your /boot/grub/menu.lst
Just follow the existing configuration

There are a couple ways to do this.

1. Keep the Grub that's already on the MBR and just add the other newer distros' /boot/grub/menu.lst entries to the original distro's /boot/grub/menu.lst

2. Install the newest distro's Grub to the MBR and hope it recognizes the other distros. I've found Ubuntu to be pretty good about doing this.

Go with number 1 - presuming the new distro allows you to install without insisting on replacing the boot-loader in the MBR.

You need to be carefull with the root directive, or (better) use absolute path directives - that way I find less errors creep in.

I run the 3 you see in my profile and have one partition for trying out different distros (Mepis at the moment) Usually I just use Yast to configure the bootloader. Don't know if this is the best way, but never have noticed a problem.
Quick edit: I'm assuming your using Grub

hi everyone,
me too follows the same path as yours.
installing 1st distros in MBR and then making entry into its grub.conf about the rest of distros ( without installing there bootloaders anywhere ).
but i always faced a problem with this methodology.
suppose my 1st distro, whose bootloader is in MBR, fails.........then???
it won't allow me to access rest of the distros.
the only solution seems to have is to restore its bootloader again using its 1st cd or through rescue floppy.
i fired a query on this issue few days back, but can't understand the solutions given to me
you should have a glimpse on that here

could anyone able to understand that...plz. explain a bit to mee too.

Yep, That is me alright. It has grew to 45+ now!

I think Grub can only be stopped by Linux's maximum limit of 255 raw devices.

Many Linux can't cross the 137Gb barrier in a hard disk so it is a bit of a struggle to have 40 to 60 partitions when only a handful of distros would dare to go to the deep end.

Come on guys booting 40 systems is no different from booting 2! Same instructions on the same /boot/grub/menu.lst
