Hi guys, i just installed a new 1 TB HD and a second 60 GB SSD with a HDD caddy that goes in place of my optical drive into my in my mid 2010, 15" MBP. The SSD will store the OS and apps and the 1TB drive for files. Neither of the drives are pre installed an OS. I formatted a small external USB HD to boot snow leopard and install with after the two HD's are in. I start up my macbook pro and hold down option right after the chime. It then shows me only the external HD with snow leopard to select. I choose it and it goes back to a grey screen with apple. I wait a while but nothing happens. What is the problem here? How can i install snow leopard onto my new SSD? Please help. Thanks!
