be able to bring to light the issue. Hightechdad Gandalfthewise Single layer DVD. When you follow the above exactly there will not be enough room on the created image for the terminal command to copy everything over and it will fail. I tried by using "single partition -- apple partition map" and discovered that this leaves more room on the image, all the files fit, and it will burn successfully to the single layer DVD.  Its verifying now, I will post here if it does not work. dto458 Alright well it's pretty much going to be the same as what you told me to do. Alright so, I mounted the InstallESD.dmg. Then clicked New Image, used all your instructions on creating the new "OSX Mountain Lion DVD" dmg. Here's a linked screenshot if you don't believe me: http://i.imgur.com/vQbeu.png . I repaired the disk again even though I'd done it twice: http://i.imgur.com/satc3.png . Then I copied the command exactly as you had it written down for. Andd this is what has happened every time: http://i.imgur.com/kGORf.png ttp://www.hightechdad.com hightechdad It's not that I don't believe you. I'm just trying to remember how I got around the same issue. Two things that I did do were:1) reboot and try it again and 2) name the image differently the next time (you can see in one of my screenshots, I added "boot" to the name. Try that. Also, which cp command are you using? I'm doing the one in my post. rrm74001 @hightechdad:disqus Look at
