Sorry, I don't know what you're asking. This bootable recovery disk can only be used install roms, restore and make backups, etc for the Nook Color. (You don't have any previous posts or list any devices in your profile.) So if you have a different image, I don't see the benefit. This IS the latest version for the NC. The bootable sdcard cannot be used for any other device.
I suspect you're asking something different tho like booting a rom from the sdcard.
