EFI
The x64 version of this build doesn't support hardware with EFI, due to the Windows Preinstallation Environment being from an x86 Windows 7 RTM build. To attempt to solve this issue, copy the build's  into an x64 Windows 7 Preinstallation Environment, or deply the image using DISM. This patch however does not work for all UEFI configurations.
