To Drop All Linked Server:

DECLARE @sql NVARCHAR(MAX)

    DECLARE db_cursor CURSOR FOR
        select 'sp_dropserver ''' + [name] + '''' from sys.servers

    OPEN db_cursor  
    FETCH NEXT FROM db_cursor INTO @sql  

    WHILE @@FETCH_STATUS = 0  
    BEGIN  

           EXEC (@sql)

           FETCH NEXT FROM db_cursor INTO @sql  
    END  

    CLOSE db_cursor  

    DEALLOCATE db_cursor

Note: It will delete even your local server details also.
