In /boot/grub/menu.lst, add after "## ## End Default Options ##" these lines

title Ubuntu 10.04 LTS, kernel 2.6.32-21-generic
uuid ef3449fc-7813-48fe-a458-1c611b17fce4
kernel /boot/vmlinuz-2.6.32-21-generic root=UUID=ef3449fc-7813-48fe-a458-1c611b17fce4 ro xforcevesa quiet splash
initrd /boot/initrd.img-2.6.32-21-generic
quiet

You have to change "ef3449fc-7813-48fe-a458-1c611b17fce4" with your own disk uuid.
When you was talk to update grub, you probably selected option "Keep Old".

Use a LiveCd and mount hard drive.
After localize new place of menu.lst.
And fix UUID.

I'm too busy these days. Sorry. If you want more help, I'm affraid you will have to wait friday.

Insert Ubuntu Cd into tray.
Choose "Try Ubuntu without using it".
You should after be in a live session of Ubuntu.

To get UUID

   ls -l /dev/disk/by-uuid/

To go to menu.lst

   cd /media

You should see one or many disk.

   ls disk* # I'm not sure of name of device

Choose one with "boot" folder inside, and go inside

   cd diskalpha # replace alpha by true name of disk
   cd grub/menu.lst
   sudo chmod a+w menu.lst
   gedit menu.lst

In my installation of 10.04, there is no file grub.lst

Perhaps the answer to this problem lies in question 110874?

Yes. In 10.04 you have Grub2.

Can you copy/paste in a terminal:
     sudo parted -l; sudo blkid
and paste the result.
Can you also tell me on which partition are 9.10 and 10.04 ?

And next time awake me friday, by posting a new message.
I have solved lot of issues of people with 10.04, but I have other activities at evening during week.
I also gained better knowledge of Grub2 that I didn't handle.

Can you help with this problem?
