so i got the spinning ball of death, restarted my computer, and now osx is gone. for the most part, it just wont load. i wait forever and then get a stop sign. popped in the osx install disk, went to the disk utility, and it wont let me repair or mount. the windows side is working fine. i dont mind reinstalling oxs again if it cant be fixed, but i do need to get my files off of there if they still exist. what happened and how do i fix it? and if/when i reinstall osx, will it effect the windows partition?
