Hi I have problem, I'm trying to create a bootable USB with OS X Lion. I have followed the steps in erasing the USB using Disk Utility, with format of Mac OS Extended (Journaled).

But when I restore the image file from Install Mac OS X Lion > Contents > SharedSupport > InstallESD.dmg to my newly formatted USB, the format changed into Mac OS Extended. I guess this might be the reason why I can't have my USB on startup.

BTW, in restoring my source is the InstallESD.dmg. Is this correct or do I have to mount it and select Mac OS X Install ESD as the source? But anyway, I have also tried that way too, but still upon startup I cannot view my bootable USB.

Also, the USB shows in the startup disk preference pane.

Is there a step that I missed?

Thanks

Follow the directions given here. They're for Mountain Lion but are exactly the same for creating a bootable Lion USB flash drive.

Have done it the way OS X Daily describes, but found Liopn DiskMaker much more simpler:-
