I have a macbook pro that I had to replace the hard drive. I installed a new hard drive. I downloaded mountain lion and burned to a DVD. I was able to power up the unit to put disk in and then shut down the system. I restarted, pressed the "c" key . it found the disk, but when I clikcked on the disc icon, another screen came up with a big ? mark inside a folder. I'm assuming it can't read the disk. I called apple support and they told that the hard drive has to be formatted and need to bring to store. Unfortunately, the apple store is far away. I was hoping to get your feedback/direction to assist me getting this up and running again. any help would be appreciated as I'm no expert.
