I downloaded the Windows 8 consumer preview on a Dell Precision 390 from XP, and I am now trying to upgrade the OS. I have a Windows 7 disk, but the drive will not read any newer disks. For example, it will read a disk from 2002 but will not read the Windows 7 disk or newer computer games. I tried getting new drivers but it says the drive currently has the most recent drivers. Will transferring a different CD/ DVD drive from another computer fix the problem? Or, can I save the OS from the disk onto a flash drive, then install it into the Dell?
