I'm trying to make a USB boot disk for a new 13" Retina MacBook Pro. I've booted using the recovery disk and told it to install on a 32GB USB stick. It downloads and then I reboot onto the SSD. I can copy the InstallESD.dmg successfully. I've then made an 8GB USB stick using the dmg image. I've tried both using Disk Utility and the Lion Diskmaker app. Both successfully make the USB stick but if I reboot onto this stick to test it, it starts the installer then get an error and quits. I've successfully down with other machines with both Lion and Mountain Lion. But it seems like the image downloaded from recovery wants to start an immediate install on the boot disk. If I boot from the 32GB stick it doesn't fail but start to immediately try to install on that drive. Anyone gotten this to work? I know that the normal Mountain Lion image can't be used because this machine needs 10.8.2 at least.
