Intro : I bought some old PowerEdge 2850s in order to setup a test/learning environment. My frustration of installing server 2008 R2 on these machines led me down different paths such as Dell SUU (which was another set of frustration with the 2850). Here is the most efficient way to install Server 2008R2. Please ask any questions in the comments below.
- Ensure that the latest BIOS is installed. (Bios A07).

The installation will scan all folders on the USB in order to perform a driver installation for the HDD; and will prevent the blue screen of death. Drivers for the 2850 in the link below.
