Try this to get Ubuntu booted (temporary fix - doesn't update anything).
At the grub menu, hit the down arrow - just to stop the countdown timer. Highlight the Ubuntu line, then hit e to go into grub edit. Enter O (capital oh) to insert a line. Enter
Code:
unhide (hd0,1)
Then hit <Enter>, and b to boot the modified entry. That should boot Ubuntu for you.

Then start backing up your data.

Alright, according to your partition manager there, you have 4 partitions on your primary hard drive, these are (hd0,0) - (hd0,3) in GRUB.

So what you need to do to get everything back is unhide the hidden partitions and


Code:
default        0

timeout        5

title        Ubuntu, kernel 2.6.20-16-generic
unhide           (hd0,0)
unhide           (hd0,1)
unhide           (hd0,2)
unhide           (hd0,3)
root             (hd0,1)
kernel        /boot/vmlinuz-2.6.20-16-generic root=UUID=bf45cb71-3b7c-49be-b6cb-9acee2536802 ro quiet splash
initrd        /boot/initrd.img-2.6.20-16-generic
quiet
savedefault

title        Ubuntu, kernel 2.6.20-16-generic (recovery mode)
unhide           (hd0,0)
unhide           (hd0,1)
unhide           (hd0,2)
unhide           (hd0,3)
root             (hd0,1)
kernel        /boot/vmlinuz-2.6.20-16-generic root=UUID=bf45cb71-3b7c-49be-b6cb-9acee2536802 ro single
initrd        /boot/initrd.img-2.6.20-16-generic

title        Ubuntu, memtest86+
unhide           (hd0,0)
unhide           (hd0,1)
unhide           (hd0,2)
unhide           (hd0,3)
root             (hd0,1)
kernel        /boot/memtest86+.bin
quiet

### END DEBIAN AUTOMAGIC KERNELS LIST

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/hda3
title          XP pro @ hda3
hide    (hd0,0)
hide    (hd0,1)
unhide  (hd0,2)
unhide  (hd0,3)
root    (hd0,2)
makeactive
chainloader    +1
Or, if you made the backup that I recommended you can copy that file back over your current menu.lst

These steps by sygoo should also work to get you into Ubuntu.

Sorry, missed that.
you'll have to unhide it first. Catch-22.

Everybody, if it's that difficult to repair or reinstall grub, I wouldn't mind that you just helped me have access to the NTFS partition, which now isn't recognised while running the live cd and I would copy all files from that Windows partition and the files from the other two partitions (ext3 and fat32) and reinstall both Windows XP and Ubuntu... I am desperate. Besides all important information like photos and other from the windows partitions, my father needs some important files from the it. I need to recover them quick or I'll get in trouble. I'll be waiting for your responses today.

Have tried the steps from the Ubuntu forums you linked earlier?
Try these:
1. Boot with any live CD (I've done it with Ubuntu Live DVD)
2. Get a root shell -> Applications / System Tools / Root Terminal
3. Make a folder -> mkdir /mnt/ubuntu
4. Check the Ubuntu partition -> fdisk -l (Mine is /dev/hda4)
5. Mount the root partition of Ubuntu -> mount -t ext3 /dev/hda4 /mnt/ubuntu (replace /dev/hda4 by your Ubuntu partition determined at the step 4)
6. Chroot the mounted partition -> chroot /mnt/ubuntu
7. Restore Grub / the initial MBR -> grub-install /dev/hda
8. Exit the shell
9. Reboot

Old image removal

512upload;
I'm a relative newbie myself, so I will not try to solve your immediate problem. Just thought I'd relate a super easy way to eliminate your old 7.04 images using the command line (instead of using Synaptic), which I saw on a posting by aysiu some time back. It has never let me down. Possibly it would not have caused the havoc, which using Synaptic might have done in your case. From the command line, enter:
sudo apt-get remove linux-image-2.6.20-15-386 (substitute the version(s) being removed. I've included the "-386" here, as that's what I have, you might have something else like 486 installed.
This will also remove the following line in your boot screen, which ends in "recovery mode". This will remove the old kernel from your machine. Has always worked perfectly for me. Hope you get your problem fixed.
