Microsoft Enterprise Platforms Support: Windows Server Core Team
Today’s blog will discuss support for UEFI with Microsoft Deployment Toolkit and other deployment tools. First we should discuss why this change is occurring. Today’s BIOS has been around for a long time. Some of the limitations include:
Unified Extensible Firmware Interface spec replaces the existing BIOS with brand new scheme. More information on UEFI can be found at http://www.uefi.org/home/. One of the improvements will be that it will remove the limitation around disk sizes. It will support GUID Partition Table (GPT) which allows for max of 16.8 million TB.
Windows only supports UEFI with 64bit Windows. There is no support for X86 OS (requires legacy BIOS fallback mode). Improvements with UEFI in Windows will allow for the following:
Many machines such as IBM, HP, and Dell are shipping today with support for UEFI. The following summarizes the support for UEFI in Microsoft deployment tools:
Windows Deployment Services: UEFI is supported
Microsoft Deployment Toolkit 2010 Update 1: Unsupported since it was not fully tested. At the time MDT was created there no production machines available for us to test.
System Center Configuration Manager (ConfigMgr): UEFI is unsupported.
If the computer emulates a “legacy” BIOS it should work fine. For example on some IBM servers they have instructions similar to this.
To install the operating system in legacy Mode, boot to the F1 menu options. Select Start Options and Legacy Only
You should contact the manufacturer of the computer to determine if it supports a legacy option and any additional steps to enable this.

Was that SCCM 2007 or 2012 beta? It it was v2007 do you have any idea if UEFI support is planned for v2012?
Can I create a single sysprepped Windows 7 64 image that can be loaded on both legacy BIOS machines and newer UEFI machines? I do not want to have to maintain multiple images just to pick up the advantages of UEFI on my newer harder.
Bump on TT-ICCDS' question. Is UEFI supported in SCCM 2012? Workarounds for UEFI w/ SCCM 2012?
here's how to deploy Windows 8 (or 7) in UEFI mode using Configuration Manager 2012 - www.niallbrady.com/.../how-can-i-deploy-windows-8-in-uefi-mode-using-configuration-manager-2012
