How can I make a bootable DVD with OS X Lion

The installer application can be executed from the DVD you burned, but the DVD is not bootable. If you want a bootable DVD you need to burn the InstallESD.dmg contained within the application to a DVD per the instructions in the linked article.

This is a very good article:

I do have a question about burning the disk.

We downloaded Lion yesterday but have not installed. We had not seen this specific recommendation, but we knew we needed to copy/burn the Lion installation software to DVD first, because if we ran the installer first it would be deleted. So, we burned the "Install Mac OS Lion 10.7 App" from the Applications folder, to a DVD. We did NOT show package contents, open contents, and copy the actual InstallESD.dmg file, to burn IT to a DVD.

My question is... do you think that the "Install Mac OS Lion 10.7" App will run from a DVD and enable installing Lion from the DVD? Or should we make another DVD with just the InstallESD.dmg file?

Thanks in advance,

I guess, Why apple didn't include a disk is that the recovery HD partition is there instead of a physical disk.

Ah.... important distinction and thanks for clarifying that for me! We will do that!

Thanks so much,

Use the Recovery HD. Reboot while holding CMD+R.
