So, my system is pretty messed up and I determined the only way to fix it is to re-install OS X, unfortunately I can't find my installation disks... I have no idea where they could be. I assume that OS X install disks all come paired with the computer or something? I borrowed a friends copy and when I tried and boot into it, it says that it can not be installed on my computer... I thought it may have just been his copy, so I tried another copy... Nothing. So what am I supposed to do? I don't have my disks and I can't boot from others.... Help?
