I have an issue where the driver for my touchpad needs to be re installed. I do not have the original disk that came with this laptop. When I choose to boot safe mode with command prompt, I'm met with the same login screen as a standard boot where I need to click a username. I've tried everything key combination I can think of, but I can't navigate around the screen. I also tried booting with a USB mouse but I think Vista needs to boot before it will install.
