I moved some files or programs into folders in drive C my hard drive. I didnt delete anything just wanted to get more organized is all. Everything worked fine intil I did a restart. Now I cant get windows to run and I am stuck on the black and white startup screen. After the memory test on the bottom of that screen it keeps saying : insert disk and hit any key to continue. Can I resolve this problem or do I have to take it to repair shop? Thanks, Jim.
