So I am having a panic attack right now. I tried resetting windows 10 just because of some problems, but I made a mistake. It was stuck resetting at 49%, and so I thought that powering the computer off and turning it back on would help. Instead, what happened was that it gave me the message "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system." PLEASE HELP.. I need this computer for work.
