I have found out my PC is compatible with Mac OS X Mountain Lion. I have tried Niresh’s OS X method because of not having an 8GB pendrive around. I have burned the Niresh OS X .ISO to DVD and booted through it. Everything went fine, I have reached language selection step.
After that I am trying to format my hard drive with “Disk Utility” and format as Mac OS X Extended (Journled) but when I click on erase it is showing me an error that it “Couldn’t format a Windows file system”. I have already installed Windows 7 and now I want to try OS X – so what am I doing wrong? How can I install it?
