An upgrade to Windows Server 2008 R2 can only be performed by launching the installation process from within the currently installed operating system. In other words, it is not possible to perform an upgrade by booting from the installation media. To initiate the upgrade process, therefore, boot the existing Windows installation (if not already running), log into an account with administrative privileges and insert the installation DVD. If the system is configured to do so, the setup process on the DVD will autorun once it is mounted displaying the Windows Server 2008 R2 installation screen:
Select the desired edition and click Next to proceed.

Read and agree to the license terms and proceed to the next screen where the options to upgrade or perform a clean installation are provided. If the installer was invoked by booting from the DVD, or the host operating system is not suitable for upgrade only the clean installation option will be provided.
