I was trying to install windows 8 on my laptop but was not able to do so as it showed error to install windows on a given partition format so following a YouTube video I had run diskpart clean command which has deleted all my data and after that I went to market but in the mean time my younger brother had installed windows to it. Now I want to recover my data back as it had some very important data from my office so please let me know if there is any method to recover the data back?
