10.7: How to get a full Lion install disc for a new MacBook Air or Pro

Open disk utility, right click on InstallESD.dmg and choose "restore". Restore it to a DVD, flash dive, etc and you should be able to boot from it in case your harddrive crashes (by holding down the option key at startup)

Thanks very much. Is 'restore' different than having the InstallESD.dmg on the 32G USK key with those extra files - all straight from the download? I'm asking because the free space on the 32G is quite large and I could find better uses for it - or would it matter if I have extra files on it besides the InstallESD.dmg file? In other words is there something about the procedure 'Restore' to an external USB which makes it into a boot disk vs just having the InstallESD.dmg from the original Lion 'capture'?

The other files you have on the usb drive aren't necessary. You have the OS X Lion disk image (InstallESD.dmg) which you need to "extract" to a disk (via the restore option, don't just open it and copy over files)

You could partition your thumb drive into separate partitions, one to restore the install image to and another for storing files. I suppose you could restore the disk image to the whole thing and copy files directly to it (although it would be quite cluttered, it shouldn't affect the install)

I would just use a regular DVD or smaller thumbdrive personally :P

Hope that helps.
