Querying the System Registry: In your WinPE environment and open a command prompt. Enter the following command:
1 | reg query HKLM\System\CurrentControlSet\Control /v PEFirmwareType |
The output will provide a value that indicates the mode:
0x2denotes UEFI mode.0x1signifies Legacy BIOS mode.
In the Absence of PEFirmwareType Value: If you don’t see the PEFirmwareType value, you might need to initialize the WinPE environment. Use the command:
1 | winpeinit |
Automating the Detection with a Script: For those who prefer automation, here’s a script that can detect the BIOS mode and execute mode-specific commands:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | @echo offwpeutil UpdateBootInfofor /f "tokens=2* delims= " %%A in ('reg query HKLM\System\CurrentControlSet\Control /v PEFirmwareType') DO SET FIRMWARE=%%Bif %FIRMWARE%==0x1 goto BIOSif %FIRMWARE%==0x2 goto UEFIgoto END:UEFI:: ajouter votre script ICIgoto END:BIOS:: ajouter votre script ICIgoto END:END |
