I have a three month old Dell Dimension 8400. 3.0 GHZ P4, 1 Gig Ram and a 160 gig SATA Hard Drive. When I got the computer I used the files and transfer (PC Relocator) utility. And had a bunch of unwanted extras that came with it. I'm having a Satellite Internet system installed and they wanted a clean install of windows XP. So I opened the owner’s manual and got out the reinstallation disk and the problems began. By the way Dell tech support's only response has been to say gee that's not right, and would send a tech sometime after Christmas. Anyway heres step by step what I did. I boot to the Dell reinstallation disk. The windows setup screen appears and loads files. The next screen says welcome to setup and offers three options. 1-to setup XP press enters. 2 To repair XP press R 3 to exit without installing XP press F3 I press enter and the following message comes up. Setup did not find any hard disk installed in your computer. Make sure any hard disk drives are powered on and properly connected. And any disk related configuration is correct.ect. Press F3 to quit. It dose this if I try repair also. Dell had me check the connections to the HD and Motherboard. They’re good. And debug the hard drive. No luck. Everything worked fine until I put in the reinstallation disk. Any help would be welcome.
