Hello everyone, I am sitting helpless with a non working new iMac and i have no idea what to do. I have a 3 tb hardrive imac and i wanted to install windows on it. Since bootcamp dont support 3tb, i followed some instructions that i fount on one of threads here. I deleted some volume disk and when i tried to create a bootcamp disk(these were all done on recovery mode with terminal) the terminal would give me an error couldn't unmount disk and i accidentally quit terminal so i don't have any disk information anymore. I tried to install osx but the imac can't read any internal disk. what should i do. Is the any way to turn my imac to factory default??
