Creating Media for Task Sequences

How to / Nasıl yaparım:

Stand-alone media

Bootable media

Capture media

Prestaged media

You can write task sequences and their related files and dependencies to a DVD or CD set or a USB flash drive. Using removable media allows you to run the task sequence on computers that do not have a network connection to your Configuration Manager 2012 site. Task sequence media can be used anywhere in the hierarchy.


You can create the following types of removable media:

Stand-alone Media:

Stand-alone media contains the task sequence and all associated objects that are necessary for the task sequence to run. Stand-alone media task sequences can run when Configuration Manager 2012 has limited or no connectivity to the network. Stand-alone media can be run in the following ways:

·         If the destination computer is not booted, the Windows PE image associated with the task sequence is used from the stand-alone media and the task sequence begins.

·         The stand-alone media can be manually started if a user is logged on to the network and initiates the installation.


The steps of a stand-alone media task sequence must be able to fully run autonomously from the network; otherwise, the task sequence step will fail. For example, a task sequence step that requires a distribution point to obtain a package or need to talk back to the MP to get additional information dynamically will fail. Common steps that are affected are: Install Software Updates, Install applications according to dynamic variable list and Auto-Apply Drivers; however if the necessary package is contained on the stand-alone media the task sequence step will succeed.


This media can be created using the create task sequence media wizard located in software library - operating systems - task sequences.

Select Stand-alone media

Choose if you want to create a CD/DVD or USB flash drive
You might want to set a password to protect the media

Select your task sequence you want to create the media for
Select a distribution point that hosts all packages referenced by the task sequence

Add variables with values you need for your deployment. If a variable has an empty value you will be asked to type in a value before you can start the deployment. Notice: prestart commands can be enabled as well.

After booting this media you need to type in the password. You can configure a static IP address using the Configure Network Settings

Confirm to run the task sequence

As configured before we have to type in a value for variable OSDComputerName. Now you can run your task sequence.

Bootable Media:

Bootable Medias contain the necessary files to start a destination computer so that it can connect to the Configuration Manager 2012 infrastructure and determine which task sequences to run based on its membership to a collection. The task sequence and dependent objects are not contained on the media; instead, they are obtained over the network from the Configuration Manager 2012 client. This method is useful for new computer or when no Configuration Manager 2012 client is present on the destination computer and no PXE Service point is available in the environment. In Configuration Manager 2012 it is now possible to provide a list of Management Points that can be contacted to get the Task Sequences advertised to the System. Furthermore, we now have the option create an internet-based media, which will contact an internet based management point.

Select Bootable media

Choose if this should become a Dynamic media or a Site-based media. A Dynamic media is able to contact several MP's provided during media creation.
Choose if you want to create a CD/DVD or USB flash drive

Decide to enable unknown client support, protect the media with a password or allow User device affinity.

Select your Boot image and provide the list of associated management points

Add variables with values you need for your deployment. Prestart commands can be enabled as well.

Type in the password to continue

Select the task sequence you want to execute

Capture Media:

Capture Medias allow capturing an operating system image created outside the Configuration Manager 2012 infrastructure. Capture media will prompt the user for input values like the image file destination location. If a Configuration Manager Client Agent is installed on the System, the Capture Media will ensure that it is sysprepped like the Operating System.

Select Capture media

Choose if you want to create a CD/DVD or USB flash drive

Select your boot image you want to use. Notice: No matter which processor architecture you plan to capture you can use both types x86 and x64 boot images. Sysprep will be executed in Full OS and except for Windows XP run from C:\Windows\System32\sysprep  folder. If a Windows XP Installation should be captured you need to manually copy the files from file (located on installation media) to c:\Sysprep directory before you start the wizard of the capture media.

Run the wizard

Select destination to capture the image file to (can be the local disk drive as well)

 Prestaged Media:

Prestaged Medias are hybrid wim files containing the Operating System image and a Bootable Media. It's booting into the Bootable Media part accessing the Configuration Manager 2012 infrastructure and running available Task Sequences. When the task sequence is executing the "Apply Operating System" step it will recognize an already applied operating system and will immediately continue at the next step. This is the perfect solution to be able to hand over this Image to the OEM vendor of your systems to have your corporate image pre-applied.

Select Prestaged media

Choose if this should become a Dynamic media or a Site-based media. A Dynamic media is able to contact several MP's provided during media creation.

choose where to create the prestaged media file.

As mentioned before a prestaged media file is a hybrid wim which needs to be applied on a target system. This can be done using a task sequence exported on a stand-alone media or using a windows PE to apply the image with dism or imagex.


If you decide using a task sequence to apply the image never use the apply operating system step because it will mess up the preconfigured BCD store and the system will not boot into Windows PE.



When you create media, specify a password for the media to control who has access to the files that are contained on the media. If you specify a password, a user must be present to enter the password at the destination computer when the task sequence runs.

When you run a task sequence by using media, the specified computer chip architecture contained on the media will not be recognized and the task sequence will attempt to run even if the architecture specified does not match what is actually installed on the destination computer. If the chip architecture contained on the media does not match the chip architecture installed on the destination computer, the installation will fail.

    Great help.  Can you please help me with something.  I am trying to create a bootable USB media.  I tried installing the 2012 SCCM on a few machine to be sure it was not my laptop causing the issue.  When I get to the part to select the drive letter for the USB I dont have any options to select.  I see the USB stick in my computer.  Would you have suggestions?

    Kindly suggest .

    @ Erik, you don't mention of you are using the console to access sccm or have it installed locally. The flash drive has to be plugged into the actual host box you are accessing sccm from. For instance if the server sccm is on is in a data center an you are RDP to that server an ran this the flash drive would need be plugged in physically to that server to see it, while if you ran the console from your computer it could see drives plugged into your computer.
