Help me Install Windows 7? CD/DVD device driver is missing

[Spooter]

Hi all,

I have installed Windows 7 on a number of PCs but im having problems with some HP Models (DC5700).

I have booted of the CD and just after I click the Install Now button I get a pop up advising that a CD/DVD device driver is missing.

Can anyone advise which device this pop up is referring to and which driver I am supposed to use?

I presumed it was something to do with the Sata Mass storage drivers so I downloaded the Intel Chipset drivers but pointed it at them but it didn't help.

I also read about changing the AHCI setting in the bios but this option doesn't appear to be available.

Any ideas?

Latest Bios

New Sata DVD Drive

New Download of ISO on new CD Tried

Different PC but same model tried. Same Problem

Im certain is relates to the whole ahci stuff but cannot get working despite trying al sorts in the bios and using the latest chipset drivers.
