I need to do a clean install - I've been having some bad issues with my new 27". Not too long ago, an Apple tech. walked me through an install on another machine. He had me insert the disk, and go to partition inside Disk Utility. We basically recreated the partition. My question is, what are the steps for doing this? I cant remember. Basically what the tech said was doing this wipes out some of the boot files that an erase and install wouldn't do. Plus it's really quick. Which is kind of strange to me - since he claimed it wiped out more than an erase. But I just need a fresh start.
