How to restore an image using a USB stick...

Hi, I'm trying to restore an image on a computer using a USB stick that has the .GHO image on it. When I'm in Symantec Ghost 11.5.1 I'm doing Local, Disk, and then from Image, I then select the image and then it gives me the a couple of options as to where I should be restoring the image. I get to the point where it says proceed with clone, although when I select OK it says it cannot perserve the file. How do I fix this?

Thanks
