I can't boot my OSX, I got my Macbook Pro a year ago(I7, redeon 6750 model) and it won't boot. After the grey screen where you choose between Windows or OSX, I get the grey screen that it starts booting the mac, and a second later I get something like a console window in windows that says a bunch of stuff about the OSX and to try and reboot to solve the problem. How can I format my Mac from this state? Is it possible to delete any trace of the OSX and make the Macbook Pro a Windows machine only? Love the hardware, hate the software.
