I have the InstallESD.dmg file that I want to use to make a bootable Lion installer DVD. All the articles I've seen say just burn the file onto a DVD, and you've got yourself a bootable Lion DVD. Well I just tried that, and then I put the DVD into my MBP, restarted, pressed the Option key to load the Startup Manager, and it did not show my DVD as a startup option. So I guess the DVD isn't bootable. How do I make the DVD bootable and load the Lion installer?
