Install Windows 2003 R2 on existing Windows 2008

Hi,

I am trying to install WIndows 2003 R2 Server on existing Windows 2008 server. When I run the 2003 cd it says no disk found. What can be the problem.

Hi, AFAIK, no matter what Windows OS you have earlier.., you should be able to boot off from the win2003 CD and should get along with installation!!

could it be a H/W problem - CD drive or CD itself..?
