Also in the mounted OS X Install ESD volume, you’ll find files named BaseSystem.chunklist and BaseSystem.dmg. Copy these files to the root (top) level of your install drive (OS X Base System.
I want to create a bootable copy of Mountain Lion, and I've been reading instructions on various forums, and they all say to copy the installESD.dmg file that's located within the Install OS X Mountain Lion.app. I was wondering, what is the difference between the two? I know once you install OS X, the app is deleted. What wouldbe the difference between copying Install OS X Mountain Lion to the USB vs copying InstallESD.dmg to the USB?
