Hi Zaigham,
This can happen when you're booted into the native WinRE instead of a USB setup disk or a Recovery disk.
Please boot the system from the recovery drive/USB setup disk and try again. You may need to change the boot order in the UEFI settings or access the one-time boot menu.
If that doesn't help, copy the system image backup to an external hard drive and restore the image from that drive. When copying to an external drive, note that the system image backup folder must be in the drive's root directory. It shouldn't be moved to a subfolder.
