If you are using at least one of either Seagate
or Western Digital
branded HDDs in the system, you can take advantage of the free version of Acronis
' imaging and cloning software provided by each of those manufacturers. The Acronis software can be run either from within Windows or from a bootable CD, which can be created once the utility is installed on a Windows system (and it is a wise to create this CD immediately). The bootable CD will be needed if ever the Windows system is not accessible.
