Hi guys, New to this forum and sorry if the question has already been asked (probably yes). One of my computers which is a Lenovo Thinkcenter has this problem. Everytime I start it up, I get that error message " 1962: no operatin system found", but when I reboot it with CTL+ALT+Delete, it loads Windows and works fine. I have to do this each time I need it. Any fix for this? I appreciate everybody's help. Optimus
