Explanation:  When you lay down a raw (non-Windows) image on a computer, the number of heads and sectors in the target partition must match the number of heads and sectors in the source partition (in the image archive). The number of cylinders in the target partition must be equal to or greater than the number of cylinders in the source partition.

Action:  Make sure to create the original image from a computer that has a hard disk with a geometry that's similar to that of the target computer.
