Windows 7 UA hangs on the device driver

[Major]

Hi, i have usually installed my unattended windows 7 well, but now in the last 4 pc of my friends, it asks for a driver and tells me: it does not find any device driver for cd /dvd...
i will explain how i have made my unattended windows 7 (drives). I slipstream 3 drivers (chipset, massstorage, lan) in the image install.wim and the other drivers during setupcomplete.cmd (Runonceex)
I want, instead to add the controller (which i think is AHCI SATA RAID) manually, i would like to siplstream it and in which image, in order to do it unatended?
Thanks

I personally would mount the boot.wim and inject the driver with DISM and then reburn the DVD. Did you mean some other method that allowed you to use the existing media?

Use an "F6 floppy"

No it doesn't need anymore to be a floppy, it can well be a USB stick - or a second cd/dvd:

and no, you do not actually press F6 anymore , you click on "Load Driver" at the screen where you choose the destination drive for the install.

BUT, the issue here may be a misleading error, see:

It seems like the Windows 7 built-in drivers can have some issues (on particular motherboard) and still the WIndows 7 pretends to have the right drivers and that the (right) ones you provide are "not compatible".
