This question already has an answer here:
I am very new to Ubuntu, and in the anxiety to install Ubuntu ended up doing a big mistake.
While installation, I chose to overwrite my current windows 7 OS; and thought that it would only format my C: However, after installation, I have found that all my partitions are deleted and data lost.
Is there a way to recover those data? I have searched across the forums, and found out about testdisk. However, I need a very detailed step by step guide, as I completely new to Ubuntu. Some of the steps in various tutorials I found seem too advanced to me.
Any help would be highly appreciated.
