Steps to proceed

First, you need to buy and download the Lion installer from the Mac App Store to a machine running Snow Leopard and compatible with Lion. After the download is complete, right-click the installer and select " Show Package Contents " to display and access the files inside the installer.

Next, open the " Contents " folder and then the " SharedSupport " folder. Inside, you will see a file called " InstallESD.dmg ". This is the disk image file that we need to use. Copy " InstallESD.dmg " to another folder outside the installer (backup to the hard drive).

Open the " Utilities " folder on your Mac and run the " Disk Utility " application, select " Burn " from the " Images " option menu or you can click on the yellow and black icon in the menu bar (menu bar).

Next, copy the copied " InstallESD.dmg " file to the hard drive in the previous operation, select it and insert the DVD into the burner (note the standard 4.7GB DVD disc), waiting for the burning process to finish, you already have a Mac OS X Lion boot DVD.

Using the newly created DVD, you can launch any Lion-compatible Mac and install OS X Lion similar to previous Mac OS X versions. It is more convenient when you can also use the Restore function of Disk Utility to create a disk image (image) for a Lion DVD and copy it to a portable hard drive. This helps install Lion for MacBook Air or Mac Mini server computers that do not have a DVD drive.
