I just purchased a new desktop for our office, and have purchased an SSD to go with it. I want the SSD to be the boot drive, so I need to clone the existing drive over to the SSD. The SSD hasn't arrived yet, but I have the desktop. Can I start the cloning process and store the cloned file somewhere in the meantime until it gets in, or do I have to have both drives installed on the same computer to get the job done?
