I am trying to install Windows Server 2008 R2 on a new Lenovo X201 or T410 laptop.
Setup halts with the following pop-up:
A required CD/DVD device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.
Note: If the windows installation media is in the CD/DVD drive you can safely remove it for this step.
The CD drive is obviously working, as it's booting from CD to get to this point.
The only thing I can think is that it is to do with the fact they have SSD disks in - but that's just a guess.
(Edit - One extra thing that may or may not be relevant: it's the 64 bit version of Server 2008 R2)
