Attempting a clean install of Windows 10 on Dell XPS 8900 from MS iso image on DVD. This is the system as delivered from Dell; nothing exotic. Installer reports missing driver for HD, DVD, or USB but with no info what device. Nothing I have tried provides the required driver. I found a couple of files in X:\Panther\Logs that may have more info but don't know how to interpret them. Any suggestions would be greatly appreciated.
