I repartitioned my hard drive the day I got it from dell and took off the Media Direct Partition. I installed Vista but a freind hit the Media Direcct button and when it tried to start, it could not find an operating system (because I had deleted the media direct partition) after restarting the computer I keep geting the same message "missing operating system" and I cant get visat to boot. I suspect the button changes a path in the boot record, but I can't find out where, or how to change it back to the vista operating system.
