Does Server 2008 R2 support UEFI PXE boot for WDS?

    Question

  • This may have already been  answered and I know that the suggestion is for server 2012. However, our existing hardware has UEFI architecture but according to the manufacturer, it does not support server 2012????"

    We are evaluating several new "tablet " clients that will require a "UEFI" PXE boot or at least we want them to use that.

    Thank you for your assistance.


    thank you, Diane

  • WDS in Server 2008 R2 does not support (properly) UEFI PXE boot. If you can't use Server 2012 WDS, you'd need to find a third party PXE Server software to accept the UEFI PXE boot on 2008 R2.

    To be accurate, you can get one of the newer devices to PXE boot if you set it to UEFI on Server 2008 R2, but it will actually boot it in "BIOS" mode (not exactly, but 2008 R2 doesn't have the correct way to detect the boot architecture and sends the wrong response to the client). The result of this is that while you can then do a single partition deployment, you can't do a multi-partition deployment because you won't be able to write to the client's BCD Store. Also if you attempted to format a GPT disk over 2TB (say 3TB) it will only create a 2TB partition.

  • Thank you. This looks like a possible solution.. Although it is limited. It loooks like for our simple needs it will work until the next budget year. Thank you for your reply.

  • Is old information still accurate ASAP!! I need step by step instructions or better yet a video, how to Deploy Windows 10 with WDS in Server 2008 R2. Other users say it works but don't give instructions or Can you recommend third party PXE Server software to accept the UEFI PXE boot on 2008 R2. Thanks

  • According to this documentation and also my own understanding,

    https://technet.microsoft.com/en-us/library/dd348499(WS.10).aspx

    , WS2008R2 *does support* MBR/BIOS x86+x64 + EFI + UEFI PXE and WDS, but *only* x64 UEFI

    , WS2008R2 *does not* support x86 UEFI (x86 UEFI devices are not commonly found anyway..)
