Installed Ubuntu 11.04 alongside Win 7 big problem

[RobertHug]

Hi All,

Here is the big problem,I have a Dell latitude E6410I with Win 7 installed on it. I wanted to install Ubuntu 11.04 on top of it and I chose to install Alongside Windows 7.I did not back up any of my data as I installed previous versions several times on other laptops and no problem happened..But this time I am out of words, The new version of Ubuntu wiped all my windows data even though I chose the first option : Install Ubuntu Alongside Windows 7.
How can I get back my data.All my work files are lost..Is there any way to recover them. I used Gparted to check my windows partitions ,I used Fdish -l to check but can not see any Windows partition .
Here is more info about the computer:

HDD : Hitachi 500 GB
Dell E 6410
Previously installed Win 7 Pro 64 bit.(Now wiped)

Please help

Fdish -l

The command is

sudo fdisk -l

Post the readout in code tags so forum members can really see if you lost windows for sure.
Other wise. Nobody will respond to your initial query.

Happy Trails, Rok
