part 1: types of media

install mac os x lion.app , should have been downloaded /applications.
right-click (or control+click) installer, , choose show package contents resulting contextual menu.
in folder appears, open contents, open shared support; you’ll see disk-image file called installesd.dmg.
launch disk utility (in /applications/utilities).
drag installesd.dmg disk image disk utility’s left-hand sidebar.


if don't have shared support folder after opening contents, i'm not sure how burn way.
