Ghost 15 recover desktop from image to a new hard drive

Hi, all,

  I have a Dell desktop Optiplex 780, it has a seagate SATA160G HDD (only one partition which is C drive). it is new but sometimes it makes noise. I already use ghost 15, make a backup/image to an external usb drive. if one day the HDD sunddenly died,  I can buy a new HDD and simply replace the seagate one.  but can I recover the whole computer from the stored image  to this new internal hard drive?  if no,  then I have to clone the seagate hard drive now with another internal hard drive, isn't it?

 

regards,

tao
