Explanation:
On the destination computer, you will create a structure for the partitions where you apply
your images. The partition structure on the destination computer must match the partition
structure of the reference computer. If you apply an image to a volume with an existing
Windows installation, files from the previous installation may not be deleted. Format the
volume by using a tool such as DiskPart before applying the new image.
