Hi, once I get my hard drive replaced, how do I go about installing OSX on the new HD? I mean, the HD won't have an OS at all, so do I just insert my install disks, boot off them, and then install OSX on the new HD? Or will the computer boot up all? I will transfer everything over from my USD backup drive- yes, I know that will take more than a little while... (coincidentally, the Seagate Barracuda is LOUD). I'm only asking because the place where I want to get the replacement itself done charges like 30 bucks to do it, but ONLY for the physical replacement and no data transfer. Hopefully the software side I'll be able to handle...
