One labelled “Source:” the other “Destination:”.įor the “Source:” box either drag the “InstallESD.dmg” file in, or click the “Image…” button, navigate to your desktop and select “InstallESD.dmg”. If you select the drive instead of the partition, then it won’t restore the disk image onto your USB flash drive.
