How do you accidentally format a drive AND install Windows on it?
Some of the guys here may be able to recommend specific programs, but never having used one I can only suggest you google "data recovery" and pick a program. You should be able to recover anything which hasn't been overwritten with Windows files. Be aware that if this is your only drive, the more you use the system the fewer files will be recoverable.
