You got me close; RedHat docs got me the rest of the way.
I'm dual-booting to Debian and RedHat using Grub. The key turned out to be a statement at the end of the Kernel statement in the grub.conf file.
From the RedHat Docs: kernel /vmlinuz root=/dev/hda5
Once I added the root statement to the kernel line, Debian booted properly. There was some discussion on the link you sent me to that I needed to copy the kernel files from the Debian /boot directory to the RedHat /boot partition; this turned out not to be necessary.
Happy, happy, joy, joy.
Thanks for your help!

This line specifies that the vmlinuz file is loaded from GRUB's root file system, such as (hd0,0). An option is also passed to the kernel specifying that when loading the root file system for the Linux kernel, it should be on hda5

To recap. Red Hat 8 on /dev/hda, with a /dev/hda1 /boot, a /dev/hda2 /, and a /dev/hda3 swap On /dev/hdb, we have: /dev/hdb1 Linux from scratch /, not yet ready to boot /dev/hdb2 Debian woody / dev/hdb3 swap
Here is a discussion dual booting red hat and Debian:

For lilo.conf, I think you need something like:
lba32 boot=/dev/hda root=/dev/hdb2 install=/boot/boot-menu.b map=/boot/map delay=20 vga=normal
default=Linux
image=/vmlinuz label=Linux read-only
image=/vmlinuz.old label=LinuxOLD read-only optional
other=/dev/hda2 image=/boot/vmlinuz-2.4.20-20.8 label=RedHat root=/dev/hda2 initrd=/boot/initrd-2.4.20-20.8.img append="root=LABEL=/ hdc=ide-scsi" read-only
If you are want to use the Debian grub package, /boot/grub/menu.lst should have lines in it like:
default=0 timeout=10
title Red Hat Linux (2.4.20-20.8) root (hd0,0) kernel /vmlinuz-2.4.20-20.8 ro root=LABEL=/ hdc=ide-scsi initrd /initrd-2.4.20-20.8.img savedefault boot
title Red Hat Linux (2.4.18-14) root (hd0,0) kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdc=ide-scsi initrd /initrd-2.4.18-14.img savedefault boot
title Debian Stable (2.4.18-11) root (hd1,1) kernel /boot/vmlinuz-2.2.20 ro hdc=ide-scsi savedefault boot
If you decide to use Debian's grub package, set up information is in /usr/share/doc/grub/README.Debian.gz.
I installed Debian, and overwrote my RH Grub setup with LILO. I've edited /etc/lilo.conf, but every time I run lilo -v, I get this:
Boot image: /vmlinuz-2.4.20-20.8 Fatal: open /vmlinuz-2.4.20-20.8: No such file or directory.
My grub.conf that was created for RedHat (knows nothing of Debian) is at http://www.officemechanic.com/grub.conf
My lilo.conf that Debian created and I edited to attempt to add RedHat is at http://www.officemechanic.com/lilo.conf
Thanks very much!

I'm working on a Pentium III system with two IDE hard drives.
I had Red Hat 8 installed on /dev/hda2, with /boot mounted on /dev/hda1. Booting via grub.
I installed Debian Woody on /dev/hdb2. /dev/hdb3 is swap, and /dev/hdb1 is a partition on which I'm building a Linux From Scratch system.
Debian boots no problem after Lilo installed, however, Red Hat no longer boots.
Please post your /etc/lilo.conf.
Once you boot to Debian, you can mount /dev/hda1 and determine what the Red Hat filenames are.
Alternative: install grub from Debian. Then use the update-grub script
to
help build a /boot/grub/menu.lst that includes all your bootable
kernels.
I'm not at all sure what I'm doing with Lilo. My problem is
compounded
by the fact that I didn't record the grub settings before Lilo wiped
them, and can't seem to mount the /boot partition on /dev/hda1 to find
out the correct path for the image and initrd. (I'm running the
latest
kernel as installed by Red Hat.)
Any ideas as to what I need to look at to figure out what I need to to
next? (Anybody know what the image and initrd lines SHOULD say for my
version of RedHat?)
Any ideas why I can't get boot to mount? I enter "mount /dev/hda1 /mnt/temp2" and get "Invalid MFT record 0 Mount: Wrongs FS type, bad option, bad superblock on /dev/hda1, or too many mounted file systems."
Are you root when you try this?
Assuming ext2 files system:
# mount -t ext2 /dev/hda1 /mnt
Thanks a bunch!
