Edit grub in 9.10

[mosaic2s]

I have installed 8.04.3 LTS after installing 9.10 in the same disk. However, the grub menu is not showing 8.04.3 for booting.

How can I edit the grub menu in 9.10? and add entry for 8.04.03.

SOLVED - ran update-grub in root terminal while in 9.10 - all the OS were picked up by 9.10 and added to grub.cfg. I can now boot into 8.04.3 LTS as well.

Could you show how you partitioned your hard disk? E.g. with a screenshot of gparted (press Alt+PrintScr when focused on gparted to take a screenshot).

Which partition did u use for 8.04, and which partition for 9.10?
If these are not separate partitions, then how exactly did you try to install ubuntu 9.10?

Could you also post the contents of /boot/grub/menu.lst?

Actually, I have been compounding many things.
Have included the gparted screen shot.

I had 8.04.3 installed and running well. Then I installed 9.10 with ext4 - that took over grub. Lack of printer support and data reading from win OS - hence i wanted to stay with hardy heron.

I wanted to modify the grub entry from Ubuntu 8.04.3 LTS, kernel 2.6.24-24 to 25. So I asked for advise, got this command listed below. That I ran and hardy heron has updated to 8.10. So I am left with no linux installation where printer will work.

sudo do-release-upgrade -d
So I downloaded 8.04.3 and installed it. But the grub did not update. hence i can not book into the 8.04.3. I need expert help here.

either to roll back 8.10 installation to get back 8.04.
Or to edit grub of 9.10 to boot 8.04.3.

I could not locate /boot/grub/menu.lst from 9.10. have included grub.cfg file.
