Crashed, and overwritten...twice...!
Chances of data recovery at this point are slim. I am afraid you will only get a small amount back in a complete format.
Do not use the drive any more, do not boot from it, re-install anything to it or even plug it in, get a professional to help scan the drive with recovery software in-case any files are still left intact.
(When you re-installed windows ... twice you have essentially overwritten the existing files on the Disk some files may still be intact, but chances are they will be few in-between with most being over written for the 2 re-installs)
