I have a MacBook Pro with Snow Leopard.
I have an image of the Installation Disk in a USB Hard Drive (Snow Leopard Partition). Then to boot the system and start using the Hardware Test software I did this:
- I change the Starup Disk to the 'Snow Leopard Partition'
- I restart holding down the 'D' key
But it shows me a gray screen and the it start from the Snow Leopard Partition. But I can't see the Apple Hardware Test software.
What am I missing here?
