Not able to connect to SQL Server

I've installed SQL Server 2008 R2 in my system but i'm not able to connect to the same from my colleague's machine which is on the same network.
Firewall is off on both systems.
Edited:
I've installed SQL Server 2008 R2 in my system the same installation is present in my colleague's system. While trying to connect to my machine from his machine using SQL Server Management studio it was showing an error as follows..
(I've used the server name for SQL management studio of my system for login)
The server was not found or was not accessible
I found a solution to this problem after posting the question but not sure if this is the correct way.
The SQL Server Browser service was stopped when i tried to connect initially. Now when i start this service from Sql server configuration Manager i'm able to connect to my machine from his machine.
1-Install SQL Server (Management Studio) on both machines
2-On your machine, run SQL Server
3-Make sure the server name is your colleague's machine IP address
4-enjoy!

Microsoft SQL Server Management Studio 2008 missing any instance of a server

So i just installed the Server Management and when i try to connect to server it gives me an error. I went to SQL Server Configuration Manager and there i dont have nothing. I have empty lists where the server instances should be. So i dont have any running local server.
So someone can tell me how i'm suppose to set some server instance or what i'm doing wrong ?
I installed the Server Management on Windows 7, 32-bit OS, and i need exacly this version of 2008 and i dont need the updated versions at this point.
SQL Server Management tool is just a GUI for you SQL Server. SQL Server is a separate installation. If you are trying to control a remote SQL Server you will need to add that to the management UI, local servers should show up automatically if you install SQL Server locally.
You can download SQL Server 2008 - Express Edition from https://www.microsoft.com/en-us/download/details.aspx?id=30438
It will install SQL Server which your Management Studio can connect.

SQL Server 2012 on windows 8

I'm trying to install SQL Server Management Studio 2012 on Windows 8. After installing, I am unable to connect to local server and when I check SQL Configuration Manager, I found out that no sql services is running. I re-installed it many times but still no luck. Why sql services is not running ?
During the install process, check that you actually install the SQL Server Database Engine and not only SQL Server Management Studio. Management Studio is only the client software to access an instance of SQL Server somewhere (locally or on a remote server), while the database engine is actually the server software of SQL Server, hosting actual databases.

SQL Server - Sharing database over different boots on local machine

Suppose I have 2 bootable partitions on my local machine with Windows 7 running SQL Server 2008 R2 on one and Windows 8 with SQL Server 2012 on the other.
Is it possible to run/attach the same database (created under SQL Server 2008 R2) on both versions of Windows so if I boot up Windows 7 I can run my application against it. And if I run up Windows 8 I can run my application up against that? Would there be any issues if I tried it - i.e logins?
Thanks,

No, that won't work.
As soon as your SQL Server 2012 version would access one of the database, it will upgrade it to the latest internal database version for the 2012 version.
And once that's happened, the SQL Server 2008 R2 cannot use that database file anymore.
The best solution for this would be to put the database on a separate server which you can access from both your partitions - and consolidate on one SQL Server version (preferably 2012). The other obvious option would be to install the same version of SQL Server on both partitions.
Everything is stored within database, so no you will not have any issues. Just remember to use not only main application database, but use the same meta-databases (aka System dbs).
In fact it works this way on failover clusters.
EDIT:
Haven't noticed you are going to run 2 different db systems. I would recommend you to use exactly the same versions of SQL server.

SQL server 2005 instance not found

I was using SQL server 2005 express edition and, therefore was limited by a data base 4 giga size. I decided to install SQL server 2005 developper (64bits) in order to be able to go beyond 4 gigabytes data base size.
The installation program run with no error message on a Windows 7 64 bits, but did not install the SQL server Management Studio. After a couple of investigations, I found out and run the installation program on CD2 SqlRun_Tools.msi which installed the missing tools. I then installed the SQL server SP3 package.
When I opened the Management Studio, the 3 instances of SQL 2005 Express where there but no SQL 2005 developer edition (new) instance was shown.
I restored the system, then removed each one of the SQL server Express instances, then fully reinstalled the SQL 2005 developper edition with its default instance name, but again no SQLserver 2005 Developper instance was listed on the SQL Server management studio. Surprise! the 3 instances from SQL 2005 Express edition (which were all previously uninstalled) were still there, but not accessible.
I have tried to access the new SQL server Developper through my code but the instance has not been found either.
All connection strings have been working for a long time with SQL Express edition and are correct.
I have also checked that SQl server and SQl browser were started.
I would really appreciate your help.
Thanks a lot.
