微软官方部署脚本中也有一段检测BIOS或UEFI的代码：https://go.microsoft.com/fwlink/?linkid=872894
其中APPLYIMAGE.BAT中有一段可以值得参考：
@echo Checking to see if the PC is booted in BIOS or UEFI mode.
wpeutil UpdateBootInfo
for /f "tokens=2* delims=         " %%A in ('reg query HKLM\System\CurrentControlSet\Control /v PEFirmwareType') DO SET Firmware=%%B
@echo            Note: delims is a TAB followed by a space.
@if x%Firmware%==x echo ERROR: Can't figure out which firmware we're on.
@if x%Firmware%==x echo        Common fix: In the command above:
@if x%Firmware%==x echo             for /f "tokens=2* delims=         "
@if x%Firmware%==x echo        ...replace the spaces with a TAB character followed by a space.
@if x%Firmware%==x goto END
@if %Firmware%==0x1 echo The PC is booted in BIOS mode.
@if %Firmware%==0x2 echo The PC is booted in UEFI mode.
