Steps to update Intel NUC BIOS using Express Remote/Silent method
Description
I need to update the NUC BIOS without any user interaction.
Resolution
Runs the Express BIOS update from a batch file without the need for user intervention. This is useful for remote BIOS updates when user interaction is not desired.
- Download the Express BIOS update file (.EB.msi) for your Intel NUC. Example:
- Download and install any utility (such as 7-Zip) that allows you to extract files from an .msi file.
- Extract files to a folder.
- Open a text editor, such as Notepad, to create a batch file that contains only the following two lines:
- DPInst.exe /q /f /se
- Shutdown /r /t 10 /c "Upgrading the BIOS. The computer will reboot in 10 seconds" /f /d p:0:0
- Command line switch notes
DPInst.exe /q Sets the quietInstall flag to ON, which suppresses the display of wizard pages, user dialog boxes, and other user messages that DPInst and Windows generate. /f Sets the forceIfDriverIsNotBetter flag to ON, which configures DPInst to install a driver on a device even if the driver that is currently installed on the device is a better match than the new driver. /se Sets the suppressEulaPage flag to ON, which configures DPInst to suppress the display of a EULA page. Shutdown /r Restarts the computer after shutdown. /t xx Sets the time-out period or delay to XXX seconds before a restart or shutdown. This causes a warning to display on the local console. You can specify 0-600 seconds. If you don't use /t, the time-out period is 30 seconds by default. /c "comments" Enables you to comment in detail about the reason for the shutdown. You must first provide a reason by using the /d option. You must enclose comments in quotation marks. You can use a maximum of 511 characters.
/f Forces running applications to close without warning users. Caution: Using the /f option might result in loss of unsaved data. /d p:0:0 Lists the reason for the system restart or shutdown. The value p indicates that the restart or shutdown is planned.
- Save the batch file:
- Save it to the same folder as the extracted files.
- The file extension must be .bat.
- Save the file as type All Files (*.*).
- Copy the folder with all files to the target Intel NUC.
- Open a Command Prompt in Administrator mode (PowerShell isn't supported):
- Click the Windows button and type Command Prompt.
- Right-click on Command Prompt and select Run as Administrator.
- In the Command window, navigate to the folder containing the BIOS update files and the .bat file.
- Type the complete .bat file name and press Enter to launch the update process.
- Windows restarts and the BIOS update process begins.
- After the update is complete, the system starts Windows.
If you’re using BitLocker to enable encryption on a system drive:
- You might run into issues when performing a BIOS update, such as having to enter a recovery key during startup.
- You can modify the .BAT file (sample below) to temporarily suspend BitLocker (and then resume after one reboot).
- manage-bde -protectors -disable C: -RebootCount 1
- DPInst.exe /q /f /se
- Shutdown /r /t 10 /c "Upgrading the BIOS. The computer will reboot in 10 seconds" /f /d p:0:0
