downgrade from vista to xp

Hello Experts

I am trying to downgrade from current vista installation to XP. However when I hit enter to chose to insall XP at the command prompt. It is giving me the following error message

Setup did not find any hard disk drives installed in your computer.
Make sure any hard disk drives are powered on and properly connected to your computer., and that any disk-related hardware configuration is correct. This may involve running a manufacturer supplied diagnostice or setup program.

Please can someone advise?

i am now able to format the drive and install fresh XP on it..

thanks for your help anyway..

This is a pretty common problem downgrading from Vista to XP...there is a tutorial here to resolve it:
But to forewarn you, it is a bit technical if you haven't done this kind of thing before.
You probably need to copy to a floppy (or pendrive) the controller driver of your machine.
On manufacturer's site or on drivers cd provided with your machine you'll find what you need.

Then immediately after the boot of xp setup you'll be able to see a message on the bottom of the screen: "Press F6 to add additional drivers" It disappear rapidly, so be fast.
After some minutes Xp setup will ask you to insert the disk with additional drivers.
Insert the floppy with the driver and you'll get the list of drivers. Try one at time if there are more than one.

You most likely have SATA drive(s) in the system.
So you will need to have a floppy drivers disk for the sata.
Or create a Slipstream disk with Sata drivers.
NLite (#6 down)
Is the best program for doing just that.

have a good one.

sorry Joshua1909:
Seems that I stepped on your toes there.
As you link does the same as what I posted.

You have a SATA Drive.
Install the drivers and you will be good to go.

thanks for the information folks...

i will try as suggested both by joshua and carrzkiss...

seems a bit confusing though , i hope i can manage it ...

Ok, but it's possible that in this way you will not use the controller and the disk at maximum performance.
This is called compatible mode.
