I have had good luck with Clonezilla for both Linux and Windows machines.  
It boots from CD and can put the image of the system in an assortment of places.
I personally, dump to one of the large external USB drives.  
Restoring to a new disk works fine so long as the disk is of equal size or larger than
the original.
