If you have "wipe" the whole HDD it's gone, you will not have it back.

If you want to try to do some data recovery you can use CAINE but being you a person that wiped out his own HDD you might not have the knowledge to do so. (sorry).

Keep the 50€ for you or invest that money to ask to a computer repair store on your town to do the job. (Search "data recovery" on Google and find somethign in your area).

But even a data recovery expert will only be able to partially recover the data; maybe some image, maybe some video but forget about complex stuff or software installed.

I'm sure next time you will remember to do a backup before you run into a Windows installation.

EDIT: or maybe try Windows File Recovery, but not sure if it could help
