Can we deploy SQL Server using windows sysprep image?
Yes. Starting from SQL Server 2008 R2, we support command line parameter to deploy sysprep windows image. For more info, refer http://technet.microsoft.com/en-us/library/ee210664(SQL.105).aspx. It is important to note that IA64 editions & WOW 64 installations are not supported by SQL Server SysPrep.
