Operating system missing error

[ericdperkins]

I get the "operating system missing_" error on power up of my lenovo ideacenter that is 4 weeks old. I have recently installed the net from Time-Warner on cable.. I called lenovo and the tech gave me the "press F2 while turning the power on to it". This works but why do I need to do this? What gives with it working and then it doesn't .... I have not moved, touched, jostled it or anything to it that I didn't do when it was first installed. It works fine but will this indicate a future of trouble? I have virus protection from McAfee is this not enough?

Make sure that the boot device order in your BIOS is correct

Make sure hard drive is first device.
