Error message when you create a new partition during a Windows Server 2008 installation on a computer that has UEFI enabled: "0x8004240f"

Expand the hotfix package

Expand the Windows6.0-KB971576-platform.msu package by following these steps:

1. At a command prompt, switch the current directory to the directory that contains the Windows6.0-KB971576-platform.msu package.
2. Type the following commands, and then press ENTER:
   md tmp
   Expand –f:* Windows6.0-KB971576-platform.msu tmp
   md cab
   Expand –f:* tmp\Windows6.0-KB971576-platform.cab .\cab
   Note When you run these commands, the files are extracted to a Tmp folder, and a file that is named Windows6.0-KB971576-platform.cab is extracted. The updated files are located in two subfolders that are named like x86_microsoft-windows-setup-component_XXXXXX. The subfolder that contains 6.0.6001 in the name is for Windows Server 2008. The subfolder that contains 6.0.6002 in the name is for Windows Server 2008 Service Pack 2.
3. Create a new folder named Hotfix, and then copy all the updated files into the Hotfix folder.
4. In the Hotfix folder, rename the Setup.exe file to Setup.exe.sav, and rename the Setup.cfg file to Setup.cfg.sav

Modify the Boot.wim file

Before you follow these steps, install the WAIK (Windows Automated Installation Kit) which is available in the following download:
Download the Windows Automated Installation Kit (AIK) package now.

1. Open the Microsoft Windows Preinstallation Environment (WinPE) command prompt by using the Administrator privilege.
2. Create a temporary directory named SetUPDVD by using the following commands:
   md SetuPDVD
   cd SetupDVD
3. Copy the Boot.wim file from the operating system that you are modifying to the SetupDVD folder.
4. Make a directory to mount the Wim file by using the following command:
   md mount
5. Use the imagex command to mount the Boot.wim file:
   imagex /mountrw boot.wim 2 .\mount
6. Copy the updated files to the Sources directory in the mounted Boot.wim file:
   cd mount\sources
   xcopy \hotfix\*.* /e
   cd ..\..
7. Use the imagex command to mount the Boot.wim file:
   imagex /unmount /commit .\mount
   

Modify the DVD content

1. Make a folder named Dvd, and then copy the contents of the DVD to the Dvd folder. For example, you can use the following commands:
   md dvd
   cd \
   cd dvd
   xcopy X:* * /e
   cd sources
   xcopy \hotfix\* * /u
   Note In these commands, the X represents the letter of the DVD drive.
2. Copy the modified Boot.wim file to the Dvd folder on the hard disk:
   copy \setupdvd\boot.wim *
3. Rename the Setup.exe.sav and Setup.cfg.sav files back to their original names in the Sources directory. For example, run the following commands:
   copy \hotfix\setup.exe.sav \dvd\sources\setup.exe
   copy \hotfix\setup.cfg.sav \dvd\sources\setup.cfg

Create an installation image

You can use the oscdimg command to create an International Standards Organization (ISO) file of the Dvd folder and to make the image a UEFI-bootable image.
