Problems adding Knoppix to Grub in Ubuntu


I just did an HD install of Knoppix. Everything seemed to install correctly. Fstab in Ubuntu loads it fine, but I am having a problem adding an entry in grub. What I currently have in grub starts to boot Knoppix and then halts with a kernel panic. I also noticed with Ubuntu that there is a /initrd.img-2.6.20-16-generic I don't see this in the Knoppix /boot anywhere. Knoppix is installed on my SATA (sda or grub=hd2) drive, it is using the swap from my IDE (hda, grub=hd0,) drive. Can anyone tell me what am I doing wrong?


Here is the Ubuntu and Knoppix entries from my /boot/grub/menu.lst


title Ubuntu 7.04
root (hd0,1)
kernel /vmlinuz-2.6.20-16-generic root=UUID=3d9d448d-e454-4fa6-90b3-da717e691648 ro quiet splash
initrd /initrd.img-2.6.20-16-generic
quiet
savedefault

title Knoppix 5.1.1
root (hd2,1)
kernel /boot/vmlinuz-2.6.19
quiet
savedefault


EDIT: I forgot to add that when I access the Knoppix partition /boot/grub, the menu.lst is empty as well as /etc the fstab being empty to.

Problem solved with new problem.

When installing Knoppix it gives three options,

Debian (Recommended)
Beginner
Knoppix

The first time I chose Debian but there where to many things missing. So I then reinstalled it using the beginner option. Now it boots fine. All I did was copy and paste from Knoppix menu.lst to Ubuntu menu.lst.

Now the new problem is this.

I have Knoppix and Ubuntu sharing the same swap partition. So when I boot Ubuntu it is looking for something, that I am guessing Knoppix stored, in the swap partition, (It says something about the partition Knoppix is installed on, sda2, and apt-get.) I have to hit crtl+D to resume normal boot with Ubuntu.

Is this problem happening because of the shared swap partition? Should I create another swap just for Knoppix? Or is there a way for Ubuntu and Knoppix to share the same swap but some command I can add somewhere to show a difference between the two operating systems when I boot either?

Well.......

The booting/swap fixed itself. I am guessing it was one of those first time running issues because once I actually signed in to Knoppix KDE (Opposed to just booting to the KDE sign in screen,) Ubuntu boots fine now.

I still wonder if I should have two separate swap partitions for each to avoid possible future issues, anyone have any thoughts?

I don't think sharing the swap should cause any problems. I've shared swap on my desktop for a while and never encountered any issues. The only thing I can think of is that setting up to hibernate can be set to save to swap. If you have things setup this way then if you hibernate in one, boot into the other then try to restore the first there could be issues. Anything short of that shouldn't cause problems.

Thanks. I will leave everything alone with that, no sense in trying to fix something that is not broken, lol. I never had that problem before so it threw me a bit when it did happen.
