Re: Error: Missing operating system

That is a sign of possible hard drive problems.  First, look in the BIOS like it suggests in the link from Vidya.  If all looks good there, did someone change the configuration of the computer like a USB hard drive?  Unplug all USB devices that are not needed and may not have been there before. See if that helps.  If not, See here:

That way files that are important can be retrieved and saved just in case things do not go as planned.  Then that will also tell if the drive is still really functioning.  If you get that far come back for further help.
