Vista crashed on my DELL XPS 1730 laptop. Again. I deleted the RAID array, created a new one and started to install Window 7 from DVD. During the initial phase of installation the setup pop ups this: Load Driver: A required CD/DVD device driver is missing... I can then insert other media to load the drivers, but it can't find any. I checked the DELL site for drivers but I can only find firmware for the drive. Which driver do I need, and where can I download it?
