I read through as many of the past posts on using Sysprep tool, but I'm still confused. Here is the issue: I back up the complete image file of my C: drive to an external USB drive each night, using 6 different schedules (Mon to Sat). The complete C: drive is small enough so that the normal compressed image is only about 7Gb. Since I use ATI as a daily backup program, if something were to happen to my computer's hard disk, I can install a new drive and restore from the ATI image file. However, if I were to have other hardware problem, say motherboard etc., then I would try to restore to another computer but then I would run into the Windows XP validation issue. And hence the Sysprep tool. Can someone describe the step-by-step process in preparation for this worst case scenario, in migrating to a new system, so that a complete image can be prepared using the Sysprep? Preferably on CDs or DVD. TIA.
