    What operating system disk are you using to install? Is it a retail version or the original OS X disk that came with your system or a gray-faced OS X disk from another system?

    i am using the gray faced. i am now in the disk utility erasing the untitled partition with zero out data.  is this okay?

    Are you using the original OS X disk that came with your system or is it one from another system? If from another system, it will let you boot and use Disk Utility, however, it won't let you install on your macbook. The gray-faced disks can only be used with the system types they are delivered with.


    If you're using the original OS X disk that came with your system, the erase and zero out data is a good way to start with a totally clean hard drive.

    One of the least expensive approaches is to buy the retail Snow Leopard directly from Apple for $20. You probably already have the 1GB of memory to run it. Call the online Apple store, which in the US is 800-MY-APPLE, or you can order it online from them too. They can probably get it to you tomorrow if you'll pay the shipping for that. It's not available via download, only on DVD.

    The 10.6 Snow Leopard DVD is back in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store to order Lion or Mountain Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
