If you don't have a CTRL-M prompt, then one of two things is happening:  1) you don't have the RAID hardware installed to enable the PERC 4e/Di RAID controller (key, battery, memory), or 2) RAID is not enabled in the BIOS.  If you have the RAID hardware, go to the BIOS Setup (F2), Integrated Devices and set the embedded RAID to RAID Enabled. You MUST first configure RAID before any disks will be presented to the OS for the installation. The missing "CD/DVD device driver" is because your installation media is corrupt.  Try different media, downloading it again, using a download manager to ensure file integrity, verifying the hash, burning the ISO at a different speed, and/or using different software or hardware. You will THEN need the drivers for the PERC in order for 2008R2 to see the virtual disk created in CTRL-M.  The drivers don't work right now, because you don't have the PERC enabled, so essentially, the device you are attempting ot load drivers for does not exist.
