I used Rescue & Recovery for image creation. I don't know what's the procedure, is it possible to boot from that external drive via USB? I never did this procedure with Rescue and Recovery before so I don't know how to do that and is it even possible?

Hard drive on my T60 died... ( But I have Image (33 GB) of my disk on another external hard disk. So, the question is... how to recover that image to my new disk? THNX
