Norton Ghost unattended restoration from USB Flash Drive

I don't know if this is possible or not, but I'm wondering if there's a way to create a full system image from a tablet PC to a USB Flash Drive, that can be booted to for unattended restoration.  I'm looking to buy a product that can meet these goals.  The USB drive needs to be BOOTABLE, and needs to unattendedly restore a base image stored on the USB Drive.  In other words, I need a pen drive that can be booted to, and, without any user intervention whatsoever, other than selecting the boot device, can restore a base image from itself back onto the source PC.  Someone told me Ghost might be able to accomplish this, but I need to know for sure before I buy.
