Hey everyone.. I haven't been around here in forever but I have an issue. While attempting to upgrade my friend's Macbook (can't remember if it's the CD or C2D) to Leopard the install crashed in the middle giving what looked like a large Terminal window with a ton of Unix stuff and a fatal error. Tried it again and it appeared to install, but when it reboots it just hangs on the Apple logo for like 10 minutes and then restarts and hangs again. We then tried to use his Tiger restore disks and the same thing keeps happening where it just hangs on the Apple logo. I attempted to use Disk Utility to erase the HD and then install, but still no luck. Also tried to hold control when booting to select the HD but it still hangs on the Apple logo. Thanks!
