Hi, I am getting my UTD disc next week sometime, and I would like to know how to do a clean install with it. Before I would put the disc in, then go into the install process through finder, the computer would reboot, and then I could access disc utility from the top bar and just erase my disc. Then I would continue and install the new OS on my blank hard drive. With the UTD disc, I hear people saying that you have to delete a file on the disc? Which file is this? How would I got about doing it? Any help is appreciated. Thanks!
