I have just re-installed SQL Server 2008 R2 in my Windows Server, but after installing the SQL Server, I am unable to open my central admin. On opening the central admin its showing me the message -
Cannot connect to the configuration database
I am unable to open any of my site collection too. On opening a site collection its showing
Cannot connect to the configuration database. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have checked my SQL Server configuration manager and there is no sharepoint instance there too, I am afraid if my sharepoint db has been deleted. If yes, then is there anyway to restore it and how to make my sharepoint site collection and central admin up and running. Any help will be appreciated.
