I just purchased a new notebook with Vista Home Premium 64-bit loaded onto it and I am a little paranoid about security. Because I bring my laptop around with me everywhere I go due to my life in general, I am a bit apprehensive about having it stolen if I need to leave it unattended for more than a few minutes at a time or in my car for several hours, as I have heard thieves doing lately. In any case, I'd rather not let anyone be able to actually ever use the thing without me being at it physically. So, I was curious if it is possible for me to use a flash drive as a way keep people from booting it up. In other words, loading a specific program or drive onto the flash drive so that the laptop will not physically boot up if the drive is not in one of the USB ports.
