Situation: I bought a MacBook Pro few months back and I put an SSD into it, installed Windows 7, then I removed optical drive and put original HDD into it's place, and formatted the drive to NTFS, removing all other partitions, including recovery. Now, I am curious about giving MacOS a try since I also bought an iPhone, but I can't convince my MacBook to install original MacOS, because with online recovery, it recognizes that there is a different hard disc (SSD) and refuses to install. So, is there a way how can I keep current configuration, buy new Mac OS, burn my own DVD, plug in USB optical drive and install Mac OS? For windows, this is a nobrainer, but I can't figure out how to do that for Mac. I just have a MBPro with an SSD, and I want to install Mac onto it. How do I do it?
