Hello everyone, I'm trying to help a friend fix his MacBook (white plastic) which has the folder with the question mark issue. I figured I'd do a clean install of Leopard but when the installation disk boots, it says it cannot detect Tiger which is necessary for the upgrade. I tried erasing the partition, but it gives me an error and stops the operation. Is there some possible way to install Leopard anyway or can someone suggest something else? Thanks very much!
