SQL Server Subquery – Return New Row and Fill One Column

I'm trying to fetch information about a database and I have the following query that prints most of it out:

SELECT Serverproperty('ServerName') AS [Server], 
       (SELECT Server_type = CASE 
                               WHEN virtual_machine_type = 1 THEN 'Virtual' 
                               ELSE 'Physical' 
                             END 
        FROM sys.dm_os_sys_info)
       AS [Virtual/Physical], 
       (SELECT ( cpu_count / hyperthread_ratio ) 
        FROM   sys.dm_os_sys_info) 
       AS [CPU(s)], 
       (SELECT CASE 
                 WHEN hyperthread_ratio = cpu_count THEN cpu_count 
                 WHEN ( ( cpu_count - hyperthread_ratio ) / ( 
                        cpu_count / hyperthread_ratio ) 
                      ) = 0 THEN 1 
               END  
        FROM   sys.dm_os_sys_info) 
       AS [Core(s)], 
       Substring ((SELECT @@VERSION), 1, Charindex('-', (SELECT @@VERSION)) - 1) 
       AS [Product Name], 
       Serverproperty('ProductVersion') AS [Product Version], 
       Serverproperty('ProductLevel') AS [Product Level], 
       Serverproperty('Edition') AS [Edition] 

Result:

This is where my issue comes in. I found a script that prints out all your instances on the server, too. Like this:

DECLARE @GetInstances TABLE 
  ( 
     value         NVARCHAR(100), 
     instancenames NVARCHAR(100), 
     data          NVARCHAR(100) 
  ) 

INSERT INTO @GetInstances 
EXECUTE Xp_regread 
  @rootkey = 'HKEY_LOCAL_MACHINE', 
  @key = 'SOFTWARE\Microsoft\Microsoft SQL Server', 
  @value_name = 'InstalledInstances' 

SELECT instancenames 
FROM   @GetInstances 

My issue is that I cannot seem to forge the first query with the second by including it in the SELECT-statement of the first script. I get the error:

Subquery returned more than 1 value. This is not permitted when the
subquery follows =, !=, <, <= , >, >= or when the subquery is used as
an expression.

How can I fix this?
I would like the result to be printed out in the form of the image below, is that possible?
