MacBook Pro Mid-2009 15" After Re-Partitioning Windows 7, Can No Longer Access OS X Partition

So, I have come to you today having gone through about every option and route to fix this issue I am having. I will give you a brief timeline for reference:

Spring 2010 -- Installed Bootcamp and Installed Windows 7 Home Premium

Summer 2012 -- Windows 7 partition was dwindling, so decided to repartition it using Minitool's Partition Wizard, which, at least I thought, worked with no issues.

Current -- Yet again, wanting to add more to my Windows 7 partition, and this is where the source of my question comes from.

So, on my Computer view in Windows 7, it shows everything correctly, the Mac partition, etc. However, when I use the Bootcamp utility, it only shows Windows as a possible disk to boot to, additionally, when I use the shortcut menu's "Restart In Mac OS X," it reboots into Windows again. When I hold the option button upon startup, it only shows Windows. Decided I needed to do a re-install, but problem was, when I held down Command + R, I do not get the Apple Recovery Options, what I get is a brief black screen, followed by Windows trying to boot up, which it doesn't and freezes. Then upon turning it off and on, I get the option to repair Windows or continue to Windows start-up.

Basically what I am saying is that I'm stuck in my Windows partition. I contacted Minitool, and they said that I needed to backup my OS X partition and then reinstall it, I backed it up, but I don't know how to reinstall the OS X, if I have no way of even accessing anything on that side of the partition and I am really getting frustrated with finding out how to fix this. At this point, I am not even sure what OS X I was running, I know it came with Snow Leopard but I don't remember if I updated it since it has been awhile since the last time I used it (Obviously, ha). Would purchasing the Boot Disk again work given that I will be running Windows? I am just asking for some advice/help on this issue, I am willing to consider all suggestions maybe outside of buying a new Mac. Currently, I am about to install Bootcamp 3.3 and then see if that has any affect on the matter after the restart. Thanks to all in advance!
