In case reybeast's suggestion doesn't change anything ... Normally (more than 9 times out of 10), getting the message CD/DVD drivers are needed/missing indicates bad media.  This could also explain why it hangs up while installing when using the SMTD DVD.  Here are some things that usually help: If it is the media itself: If it is the download/ISO that is corrupt:
Trying to get Windows Server 2008 R2 Standard installed on a Dell PowerEdge R210 Using the Dell Sys Management disk, reset RAID (first was told to do it RAID0 and then back to RAID1) and then to Deploy OS.  The system goes through it's work, reboots and prompts to insert the Win2K8R2 disk.  I insert the (Dell) Windows Server disk and get the prompt stating it's valid, click OK and then the server just sits at the grey screen and doesn't move.  I can move the mouse; however, the system NEVER gets past that point.  For a period of time, I can see the DVD LED lighting up and what not, then it just goes black If I boot directly to the Windows disk and install that way, it gets to the point to click the 'Install' button.  I do so and then get prompted that there are no CD\DVD Drivers.  I have downloaded every driver I can find to a USB and the system doesn't seem to like any of them What the heck can I do to get this thing all set up?
