How can I reinstall OS X without signing to App Store

I had Mountain Lion on my macbook pro and I wanted to reinstall it. So I formated the hard drive and tried to use "Reinstall OS X" from restore hd. I only forgot one thing, this version of system was bought by my friend and with his Apple ID. I had bought 10.6 I thing but there is no way to downgrade. How can I solve this? I don´t know anybody else with mac and I don´t have any contact on that friend. I don´t have Time Machine backup.

(Sorry for bad english.. it isn´t my mother tongue)

Thank you.

MacBook Pro, OS X Mountain Lion (10.8)

You already have an Apple ID and password - what you use to log in here.

I have never done this, but it may work. Can you log in to the App Store through iTunes for Windows?

iTunes only lets me download apps for iPhone and iPad. It doesn´t contain mac app store.

Ehm.. I though it was downloading directly the system but it just downloaded the "recovery" so it didn´t solve my problem.
