Triple Boot RedHat,Suse,and Windows??help!!!


I have installed Windows on one partition, then Red Hat, then Suse. When I went to install Red Hat, it read the windows partition fine and I could dual boot. When I installed Suse, it would read the windows partition and boot fine but it never saw the Red Hat partition.

How can I fix it so that when grub comes up in Suse, I can choose to boot windows, red hat, or suse?

Details:

Windows=hda-0-5 with cdrom drives etc.
Red Hat 9=hda7(swap is 6)
Suse 9=hda9(swap is 8)

I have read the forums explaining this stuff but I just don't get it and one was very good but I really do not want to blow away my partitions and start from scratch.

I will however, reinstall Red Hat as I noticed that I can add os to boot easier there from scratch. Either way, I do not want to start from scratch.

Thanks in advance!

ps. I need very detailed, step by step directions.

Also, a huge problem is that I do not have a floppy drive in the machine that I am triple booting.

So far I have this: Windows and Suse installed and working great. Dual booting into Windows or Suse no problem.

Now, I would like to install Red Hat 9 and config either lilo or grub so that I can choose from Windows, Suse, or Red Hat at startup.

Does that make sense?

when you installed Redhat did you choose to install the bootloader into the MBR or the partition bootsector?
What you can do is mount the redhat partition, take a look at its bootloader config file then add it to Suse's boot loader.

Right now, I only have Windows and Suse installed. I want to install Red Hat now but I don't want to unless I can get it to read all 3 os's with grub or lilo. Suse is at the / mount point on hda9 and I want to put Red Hat on the hda7 partition.

How do I install Red Hat and use Grub or Lilo so that when my machine boots up I can select which os to use.

Thanks

You don't have to reinstall redhat, if it already exists in the partition it's just a matter of adding few entries in /boot/grub/menu.lst
can you mount the Redhat partition, and post the contents of boot/grub/grub.conf in there?

1. Take note of the contents of your current /boot/grub/menu.lst file in Suse.

2. Install Redhat, let it install GRUB into the MBR, it will only detect Windows and add it to the boot menu, but don't worry about it at this point.

3. Boot into Redhat, edit /boot/grub/grub.conf and add what you have in Suse's menu.lst file, you can just add the one you boot and ignore the rest(like floppy etc).

go ahead and install Redhat, choose to install GRUB into the MBR, when its done boot into Redhat, edit /boot/grub/grub.conf and add the following:
Code:
title Suse
 kernel (hd0,8)/boot/vmlinuz root=/dev/hda9 vga=0x317 splash=silent desktop hdc=ide-scsi hdclun=0 showopts
 initrd (hd0,8)/boot/initrd
