    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.

    I would suggest trying to clone your drive, and then from there reinstalling the OS.

    To be honest by this point you'll have a difficult time recovering your data.

    Really the only way you'll have any chance is by finding some file recovery software that supports HFS+.

    You can restore via Time Machine if your backed up, without any back up it be very difficult to restore the data without specialised software. First stop using the system and back up the entire drive, you can then try the likes of EaseUS Mac date recovery, the application will allow you to recover up to 2Gb free, at least this will let you see what data is recoverable.

    Most important thing is not to change the state of the original drive as this will ultimately reduce your chances of data recovery. There is a plethora of data recovery apps, which one is best for your particular situation will require some research and potentially $$$. Unfortunately if your not backed up this may prove to be a painful lesson.
