Windows Disk partition manager says it is a 180GB RAW Healthy (Logical Drive) I have no idea what this means, if it means that the installation is corrupted, or if the GPT partition needs to be repaired (or something like that, I apologize if I say anything that makes no sense) I tried looking for the OSx partition, and it is there, but windows windows sees a 180GB partition (from the whole drive which is 300GB) which is where the OSx should be installed. Also tried going into recovery mode, but my iMac doesn't have it. When I went to the startup manager (holding down the options button) there is no option to boot into the OSx installation. Used it for a while, and didn't really see a problem (since I had no interest in going back to OSx at the time) then a few years later I wanted back the Mac OS environment for some stuff I was doing, and tried to get back to Mac os on that machine. A long time ago I installed windows 10 on my Early 2008 iMac, I made a partition for Windows, and installed it.
