SQL SERVER 2008 RTM has been released for some time and I have got numerous request about how to install SQL Server 2008. I have created this step by step guide Installation Guide. Images are used to explain the process easier. I had previously written the same article earlier. It seemed necessary to re post it again as request of me posting Step by Step tutorial has increased for quite some time.
Please follow all the steps as it is important that you do not miss any details as this is a very comprehensive tutorial.
I hope you find this tutorial helpful. If you are working with the latest version of the SQL Server, still this tutorial of installing SQL Server is valid as most of the steps are still the same.
The one thing I really like about SQL Server is the most is that it is very easy to install. I have personally installed multiple SQL Server in the past and most of them, I have installed in less than 1 hour. If you have experience with other popular RDBMS which serves the enterprise, it is quite possible that the installation will take over a day sometimes.
