Another great feature of SCCM is deploying operating systems.
Although you can deploy a whole range of Windows versions, i’m going to focus on deploying Windows 7 with SP1 included.
In order to support Windows 7 (with SP1), you’ll going to have to download and install an extra update from microsoft here kb2489044.
Also, there is an extra issue to deal with.
With the update above installed, it would be possible to support and deploy Windows 7 to known systems, meaning systems that are allready member of the domain and registered with sccm.
Since we’re talking about deploying Windows 7, it is very well possible that a brand new system has been unboxed and you want to deploy it right away. So we’re dealing with unkown systems here.
To support unkown systems, we need to have at least update R2 installed for SCCM 2007 SP2. But update R3 is out so we’re going to install R3.
Before installing R3, there’s a prerequisite here: kb977384.
Then download and install: Update R3 for SCCM 2007 SP2.
Build a reference system
The most easy way to deploy an image is to build a reference system first. This means a plain Windows 7 installation with only the essential software installed that you want to have on every pc. A virtual workstation, like one in VMWare, will do just fine.
- Download the latest installation media from Microsoft. As of this point: Windows 7 with sp1 included.
- Create a virtual machine with only the basic requirements (1cpu, 512MB ram, 24GB thin provisioned disk will do just fine). As of Windows 7 we don’t need to think about the fact that hardware we are going to deploy this image to is likely to be using a different HAL since Windows 7 will do a HAL autodetect on boot. If you don’t know what that means, don’t bother :)
- Boot the virtual machine and boot from the installation medium
- Keep all the settings default. At the point where Windows setup asks for a username and computername press Control+Shift+F3
- Windows now boots into audit mode. More on that on my website: Windows 7 Audit Mode
- Do not close the small sysprep (”Hulpprogramma voor systeemvoorbereiding”) window!!!
- Now install all the software you want. You can reboot as many times as you like, just don’t close the sysprep window. In my case i’m only installing:
- vmware client installation
- from a dosprompt: “powercfg -setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c” to set the power profile to high performance. This prevents the client from going into standby every time (very annoying!)
As you’ll see, after every reboot, Windows will automatically reboot into Audit Mode again.
- Copy the content of “C:\Program Files\VMware\VMware Tools\Drivers” to a shared folder on your SCCM server, e.g. “\\sccm01\clientdrivers\x86\vmware client\”. This is to ensure we have the appropriate drivers for this system. We’re going to need this to create bootable media for capturing this system.
- Leave the computer as it is for now
Create capture media
Capturing the installation of the reference system is done through capture media.
This is basically a Windows PE cd/dvd or usb stick that copies the content of the harddisk to a .wim file on an external disk or network share.
When you think about that, it’s easy to understand that the PE environment needs to have access to the local harddisk and network interface.
And that’s why you have to make sure these drivers are available and that’s why we have copied al the drivers to “\\sccm01\clientdrivers\x86\vmware client\” in the last step above.
Now we have to update the capture media with those drivers.
- From the SCCM Console, expand site database, computer management, operating system deployment, drivers and rightclick drivers and click Import
- Choose “import all drivers in the following network path” and browse to “\\sccm01\clientdrivers\x86\vmware client\” and click Next
- In the overview you’ll see that all drivers for the audio, mouse, scsi controller and network controllers are found. Click Next
- Click “New Package”, Name = “VMWare Client” and Drive Package Source = “\\sccm01\clientdrivers\x86\vmware client\”, select “Update distribution points when ready” and click Next
- Do not update any boot images at this point and click Next, Next, Close
- From the SCCM Console, expand site database, computer management, operating system deployment, Boot Images and rightclick “Boot Image (x86)” and click Properties
- On the tab “Windows PE” select “enable command support (testing only)” and then click the yellow icon to import drivers
- Add all drivers, one by one (although only the scsi and network drivers are really relevant) . Eventually click OK and click YES to update the distribution point, Next, Next, Close.
- Repeat the steps for the x64 boot image
- From the SCCM Console, expand site database, computer management, operating system deployment, Task sequences, rightclick Task sequences and click Create Task Sequence Media
- Select “Capture media” and click Next, select “CD/DVD set” and click browse to select an output .iso file (e.g. sccm2007capture.iso) and click Save and click Next
- Click on Browse and select the boot image that matches your installation (x86 or x64) and click OK and Next, Next, Close
Capture the image
- Make sure you have a shared folder on your sccm server e.g. “\\sscm01\images” to store the image on.
- If you are working with a physical system, make sure you have burned the iso that has been created above. If you are working with vmware, put the iso on the datastore.
- Put the capture media in the dvd player. Autorun will start.
- “Welcome to the Image Capture Wizard” click Next
- Destination = “\\sccm01\images\win7sp1referencesystem.wim” and specify the correct network credentials so that after rebooting into PE mode, the capture media knows how to store the image on the SCCM server! Click Next
- Specify the information asked, click Next and Finish
- You may see some screens popping up, just wait and the client will reboot automatically and you´ll see the System Center background and the capture in action
- If all goes well, you’ll eventually get a message “Image successfully captured …”. press OK and the client will reboot. You can then power it off.
If you let it run, it’ll do some sort of “unattended” installation, but it’s pretty useless since the machine isn’t instructed properly what to do (e.g. like joining the domain, install extra components etc).
Import the image in SCCM
- Now that the image has been captured, we have to import it to SCCM
- From the SCCM Console, expand site database, computer management, operating system deployment, Operating System Images and rightclick “Operating System Images” and click “Add Operating System Image”.
- Point to the share where the images is located, e.g. “\\sccm01\images\win7sp1referencesystem.wim” and click Next, Next, Next, Close
- Rightclick the just created Operating System Image and click “Manage Distribution Points” and click Next, select “Copy the package to …” and click Next, select your SCCM server and click Next, Next, Close.
Prepare the PXE server
- Expand (in order) site database, site management, <your site>, site settings, site systems, <your server> and rightclick your server, select New Roles, Next, select “PXE service point” + Next
- Click yes at the warning.
- Select “Enable unkown computer support” and click OK at the warning dialog
- Deselect “require a password …” and click Next, Next, Next, Close
Create the Configmgr package
- Expand site database, computer management, software distribution and packages
- Rightclick Packages, select New, Package from Definition and click Next
- Select the “Configuration Manager Client Upgrade” and click Next
- Select “Always obtain files from a source directory” and click Next
- Select UNC path and your SCCM server should have a default share called \\<SERVERNAME>\sms_<SITECODE>\ with a client folder in it, so in my case “\\Sccm01\sms_vl3\Client”. Point to that directory and click Next and Finish
- Rightclick the just created “Microsoft Configuration Manager Client Upgrade 4.0 ALL” package and select “manage distribution points” and click Next
- Select “Copy the package …” and click Next
- Select only the primary distribution point and click Next, Next, Close
- Rightclick the just created “Microsoft Configuration Manager Client Upgrade 4.0 ALL” package and this time select “Update distribution points” and click Yes
Specify network access
If we’re going to boot from the network later on, and we need to access the distribution points, we need to authenticate.
- On the SCCM console expand site database, site management, <your site>, site settings, client agents and rightclick “Computer Client Agent” and select properties.
- Click on the “Set” button at Network Access Account.
- Specify the Administrator account for now and click OK and OK
- As of a security perspective this might not be best practice but for now it’s OK
Pretty much everything is covered now.
So if we would unbox a new computer, connect all the wires and execute a network boot, this is what we would see:
In red: The WDS (or SCCM) server is not responding.
In green: the mac address of this client.
What we need to do next is create a task somehow to deploy Windows 7 to this computer.
Create a collection
- On the SCCM console expand site database, computer management, collections, and richtclick collections en click on “New Collection”.
- Name = “Deploy Win7 with SP1” and click Next
- No membership rules are needed so just click Next and click OK on the warning.
- Click Next Next Close.
Add the computer (mac address) to the collection
- On the SCCM console expand site database, computer management, operating system deployment, computer association, and richtclick computer association and click on “Import Computer Information”.
- Select “Import Single Computer” and click Next.
- Provide the desired computername, e.g.”win7-001”, and provide the mac address of the client. Click Next, Next
- At “Choose Target Collection” select the collection that we’ve created above “Deploy Win7 with SP1”, Next, Next, Close
Create a Task Sequence
- On the SCCM console expand site database, computer management, operating system deployment, Task Sequences, and rightclick Task Sequences and click on “New, Task Sequence”.
- Select “Install an existing image package” and click Next.
- Give the sequence a name like “Install Windows 7 with SP1 on new systems” and select the boot image that corresponds with the architecture, e.g. x86, and click Next
- Select the Image Package (which is your previously captured image) and at Image select “All Images” (this is because a normal Windows 7 installation also contains a 100MB boot partition). Fill in the rest of the information, like the license code and type, and click Next.
- Specify the domain to join with the right credentials and the OU you want to place the computeraccount in and click Next
- Click Browse to select the Configuration Manager package. Click Next.
- Deselect all Stage Migration settings, we’re not going to do that on new systems. Click Next
- “Don’t install any software updates” and click Next, Next, Next, Close.
Modify the task sequence
There is a small “bug” in the default task sequence if you ask me.
If you edit the task sequence, you’ll see that the network configuration is taking place before the device drivers are installed. This should be in reversed order.
- On the SCCM console expand site database, computer management, operating system deployment, Task Sequences, and rightclick the sequence created above and click on Edit.
- Select the green item called “Apply network settings” and drag it just below “Setup Operating System”
With that out of the way there is something with the partitioning to worry about:
- Select the green item called “Partition Disk” and in the “Volume” overview, you’ll see two volumes. One Primary volume with a fixed size of 100MB and one Priamary volume with a fixed size of the original disk of the reference system. Select that volume and click edit. Select “Use a percentage…” and set it to 100%. Click OK and OK.
- Select “Apply Operating System” and make sure that at “Apply operating system from a captured image” image 2-2 is selected
- Select “Apply data image 1” and make sure that at “image” image 1-1 is selected
- Drag task “Apply data image 1” above “Apply Operating System” and beyond “Partition disk”
If you want you can add custom taks or edit. Just look around, very cool! :-)
Hint: look at the partitioning settings and when formatting the disks, make sure you select quick format. Saves a lot of time!
Assign (advertise) the task sequence to new computers
- On the SCCM console expand site database, computer management, operating system deployment, Task Sequences, and rightclick the sequence created above and click on Advertise.
- Click on the browse button to select a collection and select the “Deploy Win7 with SP1” collection that we have created before. Also select “Make this task sequence available to boot media and PXE”. Click Next, Next.
- At the Distribution Point screen, make sure you also select “When no local distribution point is available, use remote distribution point” and click Next, Next, Next, Next, Close.
If you go to the “Deploy Win7 with SP1” collection, doubleclick on the “Win7-001” and go to the advertisements tab, you’ll see that the “Install Windows 7 with SP1 on new systems” is assigned to this computer.
That’s it. Perform a network boot and sit back!
