Hi everyone, I have a little problem: I have a 27 inch iMac. I'd like to reinstall Mac OS X SL from scratch. I do have the disks that came with the mac, but they got scratched really bad so whenever I put them in, restart the mac and start installing the system after formatting the HDD the installer gives me an error saying, that the system could not be installed. The disks are scratched really bad. So I went out and got the Snow Leopard upgrade DVD, put it in, restarted, but I can't pass the Apple logo, I don't even get to the spinning wheel under the logo, it just freezes and the optical drive stops (I hear it stop). I've tried pressing "c" while restarting, but nothing works. I've even tried downloading Snow Leopard from torrents and installing from a usb drive - same thing happens. Does anyone know how to fix that? Thanks in advance.
