I was wondering if anyone can help me with my problem that I have stupidly brought upon myself. I have been running windows 7 in a bootcamp partition on my 2013 MacBook pro. In my efforts to upgrade windows 7 to 8, I have managed to do a complete fresh install of windows 8 on the partition and so of course I have lost bootcamp completely. Its now basically a windows 8 computer that wont show any other drives or partitions except the one it is installed on. It wont even show the mac OS partition let alone boot into it. What a mess. If anyone can offer any help I would be very grateful.
