I have an external storage device, Western Digital, that I back up to daily. It works fine but whenever I have to do a restart, the computor ,XP pro, tries to reboot from this thing which doesn't work. I have to unplug it from the USB port, and manually restart the computor. Why can't it find the C drive for rebooting? Can I tell it to reboot from the C drive always? It's just a hassle.
