I am setting up my new MacBook Pro 17. I set it up with a 50GB second partition and when I went to set up Boot Camp, it says I need a single non partioned disc. I have reinstalled OSX having gone through the disc utility as advised but the partioned disc remains. I am back doing another run through disc utility booting from the OSX disc and can find nothing there to let me delete the partion, I have erased both discs and done a clean install. Very frustrated, can anyone advise me on how to do this.
