Hi, Having fought my way through the problem of adding SATA drivers to a machine with no floppy drive, I was congratulating myself on building an ISO image of Windows XP Professional with the extra drivers from Dell / Intel for SATA and SP3 slipstreamed in.. However, came the install all went well until I was asked for the Key. The Key that I had from the original XP Professional was typed in exactly and was rejected each time. I tried other keys with the same result. This is leaving me confused .. is this a problem in what I have done or have I missed a step somehow? Help please... anyone Best regards George
