re-image

from The Free On-line Dictionary of Computing (8 July 2008)

re-image

   <system administration> To re-install a computer's {operating
   system}, and possibly other software, by writing a {disk
   image} to the {hard disk}, replacing the entire contents.
   Re-imaging is quicker, easier and more reliable than going
   through a complete install but it relies on having a disk
   image available.

   "Sometimes if your {PC} has a {virus}, the only cure is to
   re-image it."
