Dual-boot openSUSE with Ubuntu 9.04

[Hb_Kai]

Hey,

I have just installed openSUSE intending to dual boot that and Ubuntu 9.04 but after doing so, the Grub2 menu won't recognise the Ubuntu partition.
It knows it's there but when I click enter on Ubuntu, it takes me to an error 13, I think it was.

I'm not too confident working with the Grub menus so I thought I should probably ask somewhere if someone else would be able to help me do this as I really don't want to ruin anything.

If it helps, here is what is printed when I type in the console...

linux-liuw:/home/boris # fdisk -l

I'm wanting to learn more about Linux and I do my best but this is all over my head at the minute.

Would someone be able to point me in the right direction?

Trouble is there are now two different versions of grub. The New grub2 is used by Ubuntu and the old grub is still used by Suse. I have not done this (I don't run Ubuntu) but as I understand it when installing Suse on a machine that has Ubuntu it is best to install grub to a partition and let grub2 control things. Not sure about the fix you got into and how to correct it. Maybe booting to the Ubuntu install disk and doing a repair. As I understand it the grub2 should pick up the Suse partition.

From what I can see in your menu.lst file, it looks as though Ubuntu entry should be (hd0,0).
Can you mount the Ubuntu partition from inside opensuse and print the contents of Ubuntu's /etc/fstab file?
We might be able to help more if we could see that.

Hey.
Thank you both for you replies.
Here is the contents of the /etc/fstab file

# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/sda1 during installation
UUID=7c9d3f89-10bc-44e6-acd5-b6c5b4aa6d46 / ext3 relatime,errors=remount-ro 0 1
# swap was on /dev/sda5 during installation

I just tried the booting into Ubuntu again just to see if I gave the right details here and I was partly wrong. It gives an error 15 but this is what it says anyway.

 'Booting Ubuntu 9.04, kernel 2.6.28-1-generic

I have Ubuntu 9.04 and Opensuse 11.2 installed and both use Grub Legacy. Ubuntu 9.10 uses Grub2. Where did the Grub2 come from? Did you install It or do you have Ubuntu 9.10?

You should be able to boot Ubuntu by changing the entry to: root (hd0,0) for Ubuntu.
Or you could mount Ubuntu from Opensuse and navigate to the /boot/grub/menu.lst file and copy the first Ubuntu entry to the Opensuse menu.lst.

If you do have Grub2 installed, this won't work.

The line above I assume is in Ubuntu's /etc/menulst. It should read

kernel /boot/vmlinuz-2.6.28-11-generic ....

I tried that. And Grub2 came from installing opensuse 11.2

The line above I assume is in Ubuntu's /etc/menulst. It should read

kernel /boot/vmlinuz-2.6.28-11-generic ....

That line is what appears when I try booting Ubuntu.

I couldn't find the edit button for the last reply.
The line I mentioned should be followed by

initrd /boot/initrd.img-2.6.28-11-generic

And that assumes you haven't updated your kernel in ubuntu.

So should I put

kernel /boot/vmlinuz-2.6.28-11-generic
initrd /boot/initrd.img-2.6.28-11-generic

in the /boot/grub/menu.lst under Ubuntu?

And no, I haven't updated in a few months - only recently got the internet back.

This entry is in /boot/grub/menu.lst in opensuse. Change root (hd0,1) to root (hd0,0).
Delete the line beginning 'configfile ...' and replace it with

kernel /boot/vmlinuz-2.6.28-11-generic root=UUID-7c9d3f89-10bc-44e6-acd5-b6c5-4r96d46 ro quiet splash
initrd /boot/initrd.img-2.6.28-11-generic

Then let us know if that works.
You might want to copy and paste those lines to get them right.
The whole entry should then look like this
