Err - just replace the internal drive? It seems as if somethings just not right. Only way I know how to begin all over again is to either use the original installation disc that came with your system and completely reformat the drive, losing everything, and install the OS that came with your machine, or buy a new drive and a USB enclosure for your old drive and install the new one with your installation disk to format and install the OS.
You could put the old drive in the enclosure and try to rescue as much data as you can.
Only two options that I can come up with...

For more clarification, here are some screen shots that I took of the computer view from Windows. (Note: Still doesn't give me any options when holding option and/or cmd + R on startup)
When I use a data recovery tool, it doesn't locate a MBR for the OS X partition, implying that it somehow got deleted/lost or corrupted, if that is of any help.
