You cannot provide versions of iSCSI storage drivers during installation of Windows Server 2008 R2 if the drivers differ from those on the installation media

To work around this issue, you must contact Broadcom to obtain the correct driver packages (EVBD and BXND) for Windows Server 2008 R2. Then, download these driver packages to a working directory as appropriate for the package. For example, download the BXND and EVBD driver packages to the following directories:

Then, inject these drivers into Windows Image (WIM) files. After you do this, install Windows Server 2008 R2 from the updated images.
To do this, follow these steps:

1. Install the Windows Automated Installation Kit (AIK) for Windows 7 from the following Microsoft Web site:
   The Windows Automated Installation Kit (AIK) for Windows 7
2. Create a temporary directory by using the following command and then set this directory to the current directory for all later steps:
   
   md C:\Temp\x
   cd /d C:\Temp\x
3. Create two subdirectories by using the following commands:
   
   
   
   md Win2008R2Copy
   md Win2008R2Mod
4. Copy the original DVD into the Win2008R2Copy subdirectory by using the following example command.
   xcopy N:\ .\Win2008R2Copy /e /c /i /f /h /k /y /q
   
   Note In this example, the installation DVD is in the N: drive.
5. Open a Windows AIK command prompt in elevated mode. Then, set c:\Temp\x as the current directory.
   
   Note You will use this Command Prompt window for all later steps.
6. Run the following commands:
   attrib -r .\Win2008R2Copy\sources\boot.wim
   
   attrib -r .\Win2008R2Copy\sources\install.wim
7. To mount the boot.wim image, run the following command:
   
   dism /mount-wim /wimfile:.\Win2008R2Copy\sources\boot.wim /index:2 /mountdir:.\Win2008R2Mod
   
   Note You must always use "2" for the index value.
8. To add the EVBD driver to the currently mounted image, run the following command:
   
   dism /image:.\Win2008R2Mod /add-driver /driver:C:\Temp\EVBD\evbd.inf
   
   
   To add the BXND driver, run the following command:
   
   dism /image:.\Win2008R2Mod /add-driver /driver:C:\Temp\BXND\bxnd.inf
9. To unmount the boot.wim image, run the following command:
   
   dism /unmount-wim /mountdir:.\Win2008R2Mod /commit
10. To determine the index of the desired SKU in the install.wim image, run the following command:
    
    dism /get-wiminfo /wimfile:.\Win2008R2Copy\sources\install.wim
    
    
    For example, index 3 is identified as "Windows Server 2008 R2 SERVERENTERPRISE."
11. To mount the install.wim image, run the following command:
    
    dism /mount-wim /wimfile:.\Win2008R2Copy\sources\install.wim /index:X /mountdir:.\Win2008R2Mod
    
    Note X is a placeholder for the index value that you obtained in step 10.
12. To add the two drivers to the currently mounted image, run the following commands:
    
    
    
    dism /image:.\Win2008R2Mod /add-driver /driver:C:\Temp\EVBD\evbd.inf
    
    
    dism /image:.\Win2008R2Mod /add-driver /driver:C:\Temp\BXND\bxnd.inf
13. To unmount the install.wim image, run the following command:
    
    dism /unmount-wim /mountdir:.\Win2008R2Mod /commit
14. To create an .iso file, run the following command:
    
    OSCDimg.exe /m /nt /b"C:\Program Files\Windows AIK\Tools\PETools\platform\boot\etfsboot.com" .\Win2008R2Copy Win2008R2Mod.iso
    
    Note Platform is a placeholder for the architecture of the operating system that you want to install, such as amd64 or x86.
15. Burn the file as an .iso file that is named Win2008R2Mod.iso to a DVD by using a DVD-burning application.
16. Use the DVD that you created in step 15 to install Windows Server 2008 R2.
