There is existing documentation on MSDN about How to: Install SQL Server 2008 R2 from the Command Prompt, but this post focuses on creating a silent unattended install of SQL Server 2008 R2 (Standard or Enterprise) using a configuration file. With the instructions below, you’ll be able to create a new customized SQL silent installation in minimal time. Note that the configuration below doesn’t work with the Express edition of SQL Server 2008 R2.
- Run setup.exe
- Click on the installtion tab
- Click “New Installation”
- Go through the wizard: Enter product key, accept license, install setup support files, and select the features you want to install:

- Continue the installation until you reach the “Ready To Install” step. Notice the path to the configuration file highlighted below in blue.

- Now that you have the configuration file, copy it to your own folder or network share where you want to start the unattended installation.
- Cancel setup since we’re interested in the unattended silent mode of installation; not the UI one.
- Edit the configuration file as follows:
After getting the configuration file ready, you’ll need to create a batch file that will run the silent unattended setup. Simply, create a new file ”InstallSQL2008R2.bat” with extension = “.bat” with the following content, and make sure you replace <path to SQL setup folder> and <path to config file> with the proper values.
@ECHO off
echo Installing SQL Server 2008 R2
date/t
time /t
"<path to SQL setup folder>\setup.exe" /ConfigurationFile="<path to config file>"
date/t
time /t
All we’re doing in the script above is running SQL setup.exe and passing the configuration file as an argument to it. You can download both the batch and config files here.
