In the process of partitioning my disk drive in order to run windows on my MacBook Pro, I deleted some (what I thought to be) unnecessary partitions. It was only after I got Windows booted up and installed that I realized my Mac startup disk was nowhere to be found. Now, after opening up the Internet recovery tool, I see "750GB APPLE HDD..." And then in another place I see "Mac OS X Base system". What do I do in order to recover what I can of my possibly deleted (but hopefully not reformatted) Mac OS partition? *Edit: I'm afraid if I use Internet recovery to reinstall Mac OS, I'll lose the change to recover any data.
