Important!: Updated 1/3/2015 if you have updated your 2012 R2 site to Cumulative update 3 this hotfix will not apply for your system. All of the clients in the site must be updated though as part of the cumulative update in addition to the site servers. To verify that the update is in place make sure that the client version is 5.00.7958.1401 or higher.
Once either the hotfix or Cumulative Update 3 is applied to the system, proceed to create a legacy boot wim. If the legacy boot wim is not created the task sequence will fail. Instructions to add a legacy boot wim are below:
For anyone using System Center Configuration Manager 2012 R2 and is still supporting Windows XP computers you will want to be aware of an important Hotfix that needs to be applied to the sources systems. The hotfix is explained in the following Microsoft Article (http://support.microsoft.com/kb/2910552). Failure to install this patch can result in Windows XP machines no longer being bootable and will have an error on the screen with NTLDR missing. The symptoms that we would see is that the task would fail on staging reboot, and once the user rebooted their machine they would be see the error on their screen.
Installing the Hotfix on the Site Server:
The install process is fairly straight forward, download the hot fix and apply to the primary site server. However we have found that additional steps must be completed to ensure that systems are able to use the new hotfix. Following the installation of the hotfix, four new packages are created in the Software Library as shown below.
Deploying the Client Patch
The most important package is the KB2910552 – x86 Client. This package must be installed on all XP machines. Prior to doing a Windows XP to Windows 7 / 8x migration. Failure to have this hotfix, will result in the computer not being able to boot and instead will show an error “NTLDR missing”.
Verifying the patch
Before running a task that migrates a machine from Windows XP to Windows 7 / 8x it is important to make sure that the client version has the hot fix installed. This can be done by opeing the Control Panel -> Configuration manager. In the general tab the Version should match 5.00.7958.1104
Importing ADK 8.0 media to be used with the task sequence.
Unfortunately ADK 8.1 / pe Images using OS version 6.2.9600) do NOT support booting from an XP client. As a result, an older PE Image based upon ADK 8.0 must be used (OS version 6.2.9200).
