So I have a fully functional mid-2010 Macbook which had 10.6.8 installed with a 250 GB hard drive. I bought a Seagate 1 TB hybrid SSHD and went to Geek Squad for an installation. When I brought the Macbook home, I connected a Superdrive with a Snow Leopard install disk, booted it up with "option". The Macbook recognized the "OS X Install disk", but that was the only option; I'm not sure if it was supposed to or not, but it did not acknowledge the hard drive. When I selected the Install Disk option, the Apple logo with the loading wheel below it was going for a couple of minutes but then I got a kernel panic. With a normal startup, I got the flashing question mark symbol. I tried a Safe Mode boot (with Shift key), but got a kernel panic again. Does anyone have any possible next steps? Does the hard drive have to be formatted in some way through Disk Utility? I've been scouring for options on this site, but I'm a bit of a novice when it comes to these sort of things. Thanks!
