Installing SQL server 2005 After Installing Visual Studio 2005

Question

Hello all,
I am studying C# and had Visiual Studio 2005 installed on my PC, now I need to install SQL server 2005, but it refused to be installed while Visual Studio is there, when I remove VS and all of component (SQL built in servers) it gives me loads of windows errors, Is there any way that makes me install SQL server 2005 without uninstalling VS ?

Thanks in Advance
