Recovery Solution Request!!!

In windows 7 which was on my BOOTCAMP, I used disk management to shrink Drive "C:\" and then creating one more partition. It caused the startup failure of both MAC OS and WINDOWS!

unfortunately even when I used Internet recovery and then Disk utility, I couldn't access to my partitiona and backup.

Disk Utility indicates partitions Unmounted and "windows_DLM" format type!!!

I'm Certain that when I used to shrink my BootCamp partition, I did nothing with MAC Partition.

Is there any scenario to recover data on my partitions?

and if the answer is yes, what are the scenarios?

please tell me How can I do to not loosing my data?

I read some articles about TestDisk program which is a recovery software but now I have no OS to Start from!!!

and an article describing using "dd" command in Terminal to create image, But actually I don't realize what can I do and what's the solution for such a problem occured!
