Cannot log into startup manager.
When I boot up holding the option key, this screen pops up
I enter my password and hit enter, nothing happens. I click the button to the right, nothing happens.
I want to boot from my Snow Leopard installation disc that I got in the mail, because I want to install it. I had problems with a flashing folder with a question mark in it, which is why I wanted to restore.
What can I do?
MacBook (13-inch Mid 2007)
