I am using Win server 2008 and installed SQL Server 2008 R2, when i tried to install the Share point server 2010 in the configuration wizard it gives me error as below

I tried to install the hot fix, http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=970315&kbln=en-us for x64 bit and when installing the hot fix there was no instances or services enabled to proceed further for the installation.
SQL Server version is
