Can't install OS on new HD
I installed a new hard drive in my MacBook, but cannot get Snow Leopard to install. I did the replacement according to ifixit.com and then partitioned it and ran erase. When I start up with the disk, everything seems to be going fine - the new HD shows as destination for install and the screen says it's installing the OS. It says there are 30 minutes left and then an error screen comes up that says there's a software problem and to retry. I've tried about ten times, same result. Do you have any idea what's going on and how I can fix it so I can install the OS? I've even tried installing Tiger from an old disk, but nothing at all happened - just a blank screen. Please help!
