The problem will be that you are using a OEM Copy of Windows and it doesn't support SATA Drives. This is quite common with XP and newer computers which now all tend to have SATA Drives not IDE Drives.
The solution here is to Press the [b]F6 Key[/b] when the very first Blue Screen appears on the Windows Installer and when prompted insert a floppy with the SATA Drivers copied to the Root without a folder and press enter. This will load the SATA Drivers and allow you to install the OS.
If you don't have a floppy Drive available you can make a Slipstreamed Install copy of Windows by following the directions here. I'm listing both a Online Site and a Downloadable File just in case TR is still having problems with the site

If you belong to the Point & Click Generation and prefer to use a Software application to do the same thing you can use nLite available here just remember to read the directions on line

If this is not what is required here please post back with the Specifications of your Computer and the OS that you are attempting to install so that it is possible to correctly answer your question and not just guess the most likely thing.
