I have XP, Debian/Knoppix as a HD Install, and FC3 on my laptop. They all work. I installed XP, then Knoppix, then FC3. Before FC3, XP and Knoppix went through lilo, and they both booted fine. When I installed FC3 I told it to install GRUB, and set it up to boot all three, or so I thought. It boots FC3, and XP just fine. It had a chainloader+1 thing for Debian, and I know enough linux to know that might not work. So I edited grub.conf, and copied what FC3's boot up commands were. Then I mounted the Debian partition, and looked for what the exact names of the vmlinuz and initrd were, and it turns out it was just that. Before any GRUB modifying it just gave me a semi command prompt, but said grub instead of C:\, or root, or anything. After modifying grub, Debian boots a little, then says "Kernel Panic" and that something is named wrong. What bootup commands do I need to boot Debian/Knoppix 3.6?

Can you give more details of your partition table so that I can help you out.

8 partitions
hda1 is XP
hda2 is Linux format, but not any OS, a home directory I think
hda3 is FC3
hda4 W95 Ext'd
hda5 is Debian/Knoppix home
hda6 is linux swap
hda7 is Fat32 so I can move files between linux and XP easy
and hda8 is Debian

your grub entry for Debian should be something like this

title Debian
root (hd0,7)
kernel /boot/vmlinuz root=/dev/hda8 vga=788 ro
initrd /boot/initrd.img

It works now, thanks.
