I am running ZCM10SP3 on SLES10 SP2. If I create imaging bundle and associate it to a device, do I do that to ensure the device has a clean OS and bundles reinstall fresh on the device?

Do I need to have create a ZENWorks partition on the hard drive before I can associate the imaging bundle to the device?

Very new to ZCM and like to know what ZCM can do for me.
