No way! This is what I'm trying to accomplish: I load XP Pro unattended using my bashrats pack, and maxxp's unattended installer. Got it working on about 75% of the machines we build. When it hits a desktop, a little VB program I wrote gives me a couple options. 1) run my burn-in programs such as prime95, world bench 5, 3dmark2004, and so on. Then it will compile a results report. After all this is complete, the report will forwarded over the network to my master machine then all burn-in stuff is deleted off the HD. 2) this option is to be used after the burn-in, and it will run sysprep with my modified sysprep.ini file, thereby prepping the system for customer use if they bought the OS from us. 3) If the customer did NOT buy the OS from us, I still had to load it to run my benchmark stuff but now I don't need it anymore. So I want to smear it from windows. I mean, I COULD just walk around the corner and grab my trusty f-disk floppy, but I'd love to have this as concise and easy as possible. Hope this sheds some light on why I need to wipe the boot partition while i'm sitting in it
