Q: PLEASE HELP to restore OS X

Good morning everyone. PLEASE HELP!!!

Yesterday I wanted to add a Windows 8.1 to my Macbook pro via Boot Camp and suddenly formatted (fully, even backups) all partitions... Now I have only Win 8.1 but there are several issues with the drivers, so I want to at least restore OS X... Any suggestions???

P.S. I have tried to download OS by Command+Option+R at start up and but it needs OS Lion which is not listed in the Appstore right now...

MacBook Pro, OS X Yosemite (10.10.2)

Do you see a Recovery Console if you use Command+R? If you do not, then

1. OS X: Installing OS X on an external volume - Apple Support
2. Upgrade this external disk to Yosemite from App Store.
3. If you have the Install Yosemite Application, you can also install Yosemite directly on an external disk.
4. Boot from the external disk, and then your internal disk can be analyzed, erased, corrected, if possible.
