Disappearance of windows partition

Hi,

First of all sorry for my bad english, I am French.

I had a big problem with Parallels Desktop 7 for mac whom I was trying. The windows 7 partition as well as all the associated files disappeared while I had just uninstalled a software under Windows.

Parallels closed, then all my files of my mac desktop disappeared. In fact all the elements shared with the windows partition, or that I have used in windows, disappeared. I lost a great deal of very important stuffs that I shall never have if the windows partition does not return.

When I try to boot the windows partition, I get this error code:15195

Please help my to recover my personal files!

 

Nobody can help?
