I cannot use a flash drive recovery method either because I can't even run the. Right now I am only able to boot into windows which is where I am posting this from. I tried both erase and partition options in disk utility. So I basically cannot boot into osx itself (because I just get to the install osx screen and my macintosh drive, where I want to install osx, isn't even showing up), and I also cannot do anything from my recovery partition. Anyone know how I can restore/erase my drive completely?

I think it is unable to unmount my bootcamp drive? Tried erasing the whole drive (500.11GB). >Macintosh HD (Greyed out, repair failed) What I see in my disk utility from recovery: So I went into my recovery partition and ran disk utility. All I saw were my 650mb recovery drive and my bootcamp drive, both locked. So I booted into lion, ran mountain lion, and after installing and restarting, I was taken to a sort of recovery window, asking me where I wanted to install lion. Today I tried to upgrade to mountain lion. Mount anyway? To which I would always click yes. After using windows for a while, I would always get an error message saying "Macintosh drive may be damaged. terminal script commanddiskutil listdiskutil unmountDisk force /dev/disk2 (input te disk you are using)Please leave a comment if you have any questions.

I have a 500gb mac drive, with a windows bootcamp partition on it.
