Lion recovery USB image to DVD

hallo, have problem os x lion because want make recovery dvd system new ssd.

have snow leopard disc came 2011 mbp save time want have dvd lion, have made usb recovery tool apple. problem recovery tool uses 16gb of usb, apart dont want use gigabytes recovery tool, need use files (which bit more 15gb).

knows how lion iso/dmg file usb make new dvd? partition doesn't appears in disk assistant or finder, big problem actually.

this procedure create bootable recovery cd. not need make dvd recovery image small, contains base image of system, i.e. enough booted tools allow start recovery. reason space taken on 16 gb usb drive once dedicated recovery drive cannot used else. think better served creating on small usb drive (4 gb = less $10), boot lot quicker. booting cd takes several minutes.

open terminal window , enable debug menu in disk utility: (copy , paste code below)

defaults write com.apple.diskutility dudebugmenuenabled 1

start disk utility, go debug menu , select "show every partition"

insert usb recovery disk or conversely can create image recovery partition on mbp

select recovery hd partition (either on usb or on mbp - greyed out) , click on "mount"

recovery hd visible in finder

in disk utility go file menu , select new….disk image folder

select recovery hd in sidebar , select "image"

prompted save new image - call whatever want , save desktop

asked authenticate continue

new image created , mounted automatically

insert blank cd (just click ignore when system asks it)

click on new image in disk utility , select "burn"

disk burn, verify , eject

unmount recovery hd , uncheck "show every partition" debug menu

turn off debug menu in disk utility - in terminal:

defaults write com.apple.diskutility dudebugmenuenabled 0

done !!
