How to reinstall SQL 2005 in Windows Server 2003 for SBS?

[Guest TFS]

I've got a Windows Server 2003 for Small Business Server. It had got SQL

installed. But then SQL was uninstalled. Now I need to put SQL back in, but

I don't see how!

 

There're three CD-Rom but I don't see how and from which CD to install back

SQL.
