Hi , I had a triple boot of vista, ubuntu, kubuntu installed on my system , but due to some messing up I ended up with deleting my ubuntu partition , then I used testdisk from kubuntu to recover the lost partition , but somehow I have lost my entire window vista partition and my kubuntu partition also.
My earlier partitions were in the order
1 Dell Utility
2 Windows vista
3 Recovery
4 extended
a) I (NTFS)
b) J (NTFS)
c) ubuntu 9.10
d) kubuntu 9.10
but now I am left with only I (NTFS) . I really need to recover my lost ubuntu partition as I had some important data stored in it.
Please help.

Clone it...

You might make a cloned copy of what you have left after your first recovery attempt. You can use the command "dd" , often mentioned and documented here on LQ, or Clonezilla. Cloning gives you a chance to try a recovery more than once, perhaps gaining useful information and elimination possibilities with each try.

You need to post more details about what you tried if you hope for a qualified response to your problem.

You mentioned nothing about a backup copy of your files; next time perhaps?

Most importantly, don't write anything to disk. Anything you need to do to fix the problem should be done via live-cd/rescue disk with any hard disk partitions mounted as read-only.

More info is needed:
Which boot manager are you using?
Post fstab file where possible.
Post output of "fdisk -l /dev/sda"

Well, by mistake I deleted my Ubuntu partition and then or rebooting the system and selecting ubuntu it gave an error "device not found" quite justified. So in order to recover this lost partition I used testdisk in kubuntu , and found out my lost partition using deeper search...but then after completing testdisk when I rebooted the system ...there was no grub and the grub rescue command prompt was shown ..it was then I found out that Boot of C drive of windows vista was also lost along with kubuntu.I have not written anything to disk understanding the gravity of the problem .
Here is the output of sudo gpart /dev/sda using a live cd

This is the output of fdisk -l

After running testdisk I have my entire hd lost.

Now whenever I run parted and print anything it says
Can't have a partition outside the disk!
This is becuase for /dev/sda4 it shows end as 38914 while I have only 38913 sectors .So anybody please help me to fix this usnig fdisk, cause I am really nervous this time...
