I have tried to use my snow leopard disk to install it so I can update it to lion. I have a new 2011 MBP, but nothing I do will get it to install from the CD. I have started it up and pressed nothing, it leads me to a terminal looking background and a message saying i need to restart. I have tried holding C down to get something I have tried command C I have tried command R to get into the options area and still nothing has worked. How do I get it to install from the DVD? holding down the option key also brings me to the terminal looking screen asking me to reboot after I click on the install DVD logo. is my drive bad?
