lost Ubuntu in GRUB after 11.2 install

English Install/Boot/Login
#1

Here is the output from my computer below. I get an Error 15 message when I pick Ubuntu from the suse GRUB on booting; thus, I cannot boot into Ubuntu. I can see the files fine via SUSE. My question is: How do I get the suse GRUB to let me boot into ubuntu? Thanks!

One thing is for sure this:-

configfile /boot/grub/menu.lst

Will never work because Ub* 9.10 doesn’t use Grub Legacy it uses Grub2!

Have a look here:
https://wiki.ubuntu.com/Grub2

I make a guess at the entry is try this

###Don’t change this comment - YaST2 identifier: Original name: Ubuntu 9.10, kernel 2.6.31-14-generic (/dev/sda1)###

root (hd0,0)
configfile /boot/grub/grub.cfg

That assumes SUSE has the partitions correct.

#3

When I try to change it to grub.cfg via the Boot Loader in suse 11.2, it gives me an error saying I’m using an unallowable character in editing. Don’t know why that is. I used ubuntu live CD but that didn’t work for me either. I guess I’m wondering what methods there are to allow me to boot into SUSE and the partitions on the other hard drive with Ubuntu on them.

#4

do this in a terminal:

kdesu kwrite /boot/grub/menu.lst

or if you use gnome

gnomesu gedit /boot/grub/menu.lst

I make no promises this will work
In Yast. You could follow this guide

go to Yast → System → Boot Loader. The Grub configuration screen comes up with the Tab “Section Management” activated. In the lower right is a drop-down selector labelled “Other”. Select from “Other” the option “Propose New Configuration” and then wait for Grub to analyse your partitions and display a new configuration. This may take a while. Important: When that finishes, activate the tab labelled “Boot Loader Installation” and select to “Boot from the Master Boot Record”. [Yast will often default to booting from the root or boot partition rather than from the MBR but that’s for experts only – always choose the MBR.] Then click Finish to save the changes and install the reconfigured Grub into the hard drive’s MBR. If you get a message that "The bootloader boot sector will be written to a floppy disk … don’t bother with the floppy – just click OK to proceed and install to the MBR. Reboot and you should be able to boot to Ub

Another option would be to repair Ub* grub and use that to boot suse. I can walk you thru that if you need. Just don’t panic.
Remember super grub disk will boot anything.

Thank you so much caf4926!! That entry that you put in for the last post did indeed work, and I now can boot into Ubuntu and OpenSuse from the opening GRUB menu for suse! Comparing the two operating systems, I really have grown like SUSE quite a bit since installing 11.2. Thanks again!

#8

Yes Carl, that’s right

#9

You are welcome.

Thanks to @swerdna for his wonderful guide too.
(Hey John, Ub* is using Grub 2 now, it’s quite different. I’m working on a tutorial for it)

#10

Great.
Q1: How are you getting Grub2?
Q2: When does openSUSE plan to change over?

#11

I have a VM disk split in to dual boot: XP and Ub 9.10
Ub* has Grub2 (well it’s still beta! actually)

So at the moment I breaking grub and re-installing it - Easy enough to break, just run fixmbr from the xp cd.
Then boot the Ub live cd - open a term and what you do is fdisk -l to see your partitions, mount your Ub root @ /mnt
You could follow this, it’s good
https://wiki.ubuntu.com/Grub2#Recover%20Grub%202%20via%20LiveCD

If it doesn’t pick up XP. No worries. Boot Ub from the new grub
And from the installed sys - open a term and do: sudo update-grub

XP will appear next boot

It just works

Interesting link. Thank you

It works for me:
