Q: Recovery 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!

    Please use How to install OS X on an external drive connected to your Mac - Apple Support to install OS X (even if it is an older version offered by Internet Recovery) and upgrade it, till it matches your internal disk OS X version and then boot from this disk. Your internal disk can be inspected and can be corrected after we look at the disk partitions.

    Dear Loner T

    First of all, thanks a lot for your reply

    I'm concerned about If we install new Mac OS on my Mac, maybe we loose or decrease the chance of recovery because in installation process we have to do format process which is necessary to continue installation.

    hum?

    You cannot use a TM Capsule. If you have a 32+GB external USB disk, you can install OSX on such a disk. A USB2/USB3 flash drive can be used, but it will be slow.

     

    Please ensure that the version of OSX matches your internal disk OSX version.

    I did something which must tell you.

    after that failure I described, during system startup, windows 7(not Mac OS) tried to start but after splash screen of windows 7,it couldn't startup & restarted. even when I pressed option key(Alt key) when startup, in that menu only windows was available and there was no Mac OS.

    Suddenly I decided to test if I can do something with that not-Healthy windows 7!? then I used windows 7 installation DVD and then installed windows 7 on the same partition which my old windows was. (without any format request from wizard)

    After installation completed, windows started up very responsive and I saw windows.old folder and other my documents  in my computer. All of them are healthy.(it was hopeful thing)

    Because all my important files were in Mac OS partition (about 700GB) it is necessary to recover those partition yet.

    Now with this my new adventure, Do you think we could do such a kind of process like this one, for Mac OS as well? or that strategy you suggested before, is still the best we can do?

    please Let me Know.

    sorry for long context.

    If you install Bootcamp drivers on the newly-installed Windows, and check in Control Panel, do you see a Bootcamp item? If yes, then select it and try to restart in OS X.

     

    If that does not work, then we will need to pursue the external disk method.

    Nice!

    After installation of newly-installed Windows, I setup Bootcamp drivers and when the computer restarted, newly-installed Windows couldn't startup again! But when I restored the windows to the time before Bootcamp drivers setup, Again windows started up and was responsive.

    So as you told, it seems better to pursue the external disk method.

    According to How to install OS X on an external drive connected to your Mac - Apple Support I decided to use an SDHC (Silicon Power Elite UHS-I U1 Class 10 85MBps microSDHC With Adapter - 32GB), are you agree? is it fast enough?
