Hi, i have just installed windows 8 through bootcamp for the sole purpose of being able to play some old games i have. I managed to get windows working after buying a new keyboard as the apple keyboard and magic mouse were not recognized by windows. All was good until i came to switch back to OSX and found i was unable. It will boot into windows no problem but as soon as i hold the alt key on the new keyboard neither will boot up and i do not get the option of which to choose the screen just stays blank with a amber power light as if nothing is going to it (it normally goes green when the computer connects). I would like to keep the windows partition but if its not possible it wont be the end of the world if i have to get rid of it. Any help and advice would be greatly appreciated.
