I just installed Windows 8 on a partition on my SSD. I found out that the partition I created was not big enough, and wanted to extend it. I used a 3rd party program on Windows to do so, but now it seems that everything on my Mac partition got deleted! When trying to select boot disk on the computer, the Macintosh HD does not appear. Is there anything I can do?? Is there a chance my files are still on it, that it is just not bootable? I have no problem in re-installing, but I did not take backup on some files that I would really prefer not to lose. ---------- Also, the partition does not appear on the list of volumes to install OS X on.
