2223832 "Boot failed" error when you start a UEFI-enabled computer from a Windows 7 or Windows Server 2008 R2 installation DVD (Package 2)

Installation instructions

You can integrate this hotfix into the installation media. This hotfix must be applied together with hotfix 2223832.

There is no particular order in which to apply these two hotfixes. These hotfixes must be applied to the Boot.wim file. The Boot.wim file loads the Microsoft Windows Preinstallation Environment (Windows PE) in order to install Windows. If you use Windows PE 3.0 to install Windows Server 2008 R2, the Boot.wim file is in the Windows PE image. If you use an installation media to install Windows Server 2008 R2, the Boot.wim file is in the installation media.

Note If the installation media is a DVD, you have to burn a new DVD that has the updated Boot.wim file.

The following steps integrate this hotfix into an image for an x64-based version of Windows 7 or of Windows Server 2008 R2.

Note You must have one of the following programs for Windows 7 or for Windows Server 2008 R2 installed to create the installation media:

• Windows Automated Installation Kit (WAIK)
• OEM Preinstallation Kit (OPK)

1. Copy the Windows installation DVD files to the hard disk drive. For example, copy the files to the C:\bin folder.
2. Make any additional customizations if they are required. This step is optional.
3. Create a temporary folder. For example, create the C:\982929 folder.
4. Download this hotfix, and then run the following command to extract the Windows6.1-KB982929-x64.msu file into the temporary folder: 
   417821_intl_x64_zip.exe –x
5. Use the following commands to view each store-keeping unit (SKU) or index in the .wim file:
   Dism /Get-WimInfo /WimFile:<pathto>boot.wim
   Dism /Get-WimInfo /WimFile:<pathto>Install.wim
   Important Install the drivers into the Boot.wim file and into each SKU of the Install.wim file that you want to use. If you apply the hotfix into only one index, the hotfix is not available to the other indexes.
6. After you decide that you want to apply the hotfix to a certain index number, mount the .wim file, and then apply the hotfix.
   
   To do this for the Boot.wim file, follow these steps:
   
   1. Run the following command to create a Mount folder:
      md c:\Mount
   2. un the following command to mount the Boot.wim file:
      Dism /Mount-Wim /WimFile:c:\Bin\Sources\Boot.wim /Index:<index number> /MountDir:c:\Mount
      Note The placeholder <index number> represents the certain index number that you have selected. You have decided to apply the hotfix to this certain index number.
   3. Run the following command to apply the hotfix:
      Dism /image:c:\Mount /Add-Package /PackagePath:"c:\982929\Windows6.1-kb982929-x64.msu"
   4. After the hotfix is applied successfully, run the following command to unmount and to commit the .wim file:
      Dism /Unmount-Wim /MountDir:c:\Mount /commit
      Note To avoid an unmount operation failure, close any command windows or any explorer windows that are open in the C:\Mount folder or in the subfolder of the C:\Mount folder.
   To do this for the Install.wim file, follow these steps:
   1. Run the following command to create a Mount folder:
      md c:\Mount
   2. Run the following command to mount the Install.wim file:
      Dism /Mount-Wim /WimFile:c:\Bin\Sources\Install.wim /Index:<index number> /MountDir:c:\Mount
      Note The placeholder <index number> represents the certain index number that you have selected. You have decided to apply the hotfix to this certain index number.
   3. Run the following command to apply the hotfix:
      Dism /image:c:\Mount /Add-Package /PackagePath:"c:\982929\Windows6.1-kb982929-x64.msu"
   4. After the hotfix is applied successfully, run the following command to unmount and to commit the .wim file:
      Dism /Unmount-Wim /MountDir:c:\Mount /commit
      Note To avoid an unmount operation failure, close any command windows or any explorer windows that are open in the C:\Mount folder or in the subfolder of the C:\Mount folder.
7. To apply the hotfix to any additional indexes in the .wim files, repeat step 5 and step 6.
