I had a computer that was up in the showroom of my dealership and it had no windows os on it. It was used just to play videos for the new cars. I am trying to load windows xp on it but it says that it cannot detect the hard drive. The jumpers are right the cabling is right and everything has power. What am I missing??? Everything in the cmos is like it should be, it boots from the xp cd and starts going through setup then it comes to the scree where it says to install xp press enter and when I do it says windows did not detect a hard drive. Thanks.
