If the machines are pretty much identical, clonezilla should work. Boot the
machine with a 'clonezilla-live' CD or USB drive. If you can attach the target
drive to the same machine you can go disk->disk. Otherwise, connect to
something on the network with enough space to hold the image (ssh, nfs, or a
windows share) and clone disk->image, then boot the target machines and copy
image->disk. There is also a server version that will pxe-boot the targets if
you need to do a large number of them.
