Hi & welcome.
Theres no easy way of doing this without the help of 3rd party data recovery programs.
Ive had a few bouts of success with ontracks easy recovery in RAW mode, but as it generates filenames such as File1.xxx file2.xxx filexx.xx etc it can be a pain trying to recover the files you require.
I would rule out a complete restore to the previous state unless you are very very lucky.
Obviously you have just realised how powerful Ghost is ;(
people have had more success with GetBackData for NTFS but i havent tried that myself.
