» Description
The following error message may appear when installing Windows XP on a Dell Dimension 8400 computer:
Setup did not find any hard disk drives installed in your computer. Setup cannot continue. To quit, press F3
This issue may occur if the following conditions are true:
The computer has a Serial ATA (SATA) hard disk drive.
The SATA hard disk drive is not configured as a member of a Redundant Array of Inexpensive Disks (RAID) array.
Note:
A RAID array is generally used as a fault-tolerant hard disk drive configuration. For example, two hard disk drives may be configured as a mirror set. This kind of RAID array is known as RAID 1. In this kind of RAID array, information on one hard disk drive is duplicated on the second hard disk drive.
The SATA Operation option in the computer Basic Input Output System (BIOS) is set to RAID Auto/AHCI instead of RAID Auto/ATA.
This issue does not indicate a hardware problem. This is a configuration issue. By default, a Dell Dimension 8400 computer is configured to start (boot) from the RAID array. To start the computer from a SATA hard disk drive that is not a member of a RAID array, the BIOS settings must be modified.
To resolve this issue, modify the computer BIOS to set the SATA Operation option to RAID Auto/ATA.
This article contains step-by-step instructions to perform this action.

In this scenario, press the <F Lock> key to enable the function keys, and then press the <F2> key to enter the computer Setup program.
In the Setup screen, press the down arrow key to select Drives, and then press the <Enter> key to expand the Drives node.
Press the down arrow key to select SATA Operation, and then press the <Enter> key to select this option.
Press the right arrow key to select RAID Auto/ATA, and then press the <Enter> key.
Press the <Esc> key to exit the Setup program.
Press the right arrow key to select Exit, and then press the <Enter> key. The computer restarts.
