Error Message:

DrvLoad: Unable to load X:\InstalledDrivers\...\e1d6432.inf (Error 0x80070002)

Problem:

When WinPE is attempting to load a driver, it fails.

Cause:

When going through an OSD or Provisioning task , WinPE uses drvload.exe to access drivers. If drvload.exe is unable to load a driver successfully for use, different actions can fail, including making network connections which are required for performing OSD and Provisioning tasks.

Solution / Workaround:

• Load the drivers' .inf file onto a thumb drive and attach to the machine that is booting into WinPE.
• Identify the thumb drives assigned drive letter
  • Open a New Console

• Type diskpart then press Enter.

• Type list volume then press Enter. This will dislay assigned drive letter.

• Identify the drive letter for the thumb drive.
• Type exit and press Enter.

• Next try mounting the driver from the thumb drive using the command: X:\Windows\System32\drvload.exe [usbDriveLetter]:\[path_to_driver]\[driver_name].inf

Example: The driver in this example is located on the root of C:\

X:\Windows\System32\drvload.exe C:\e1c6432.inf

• If the driver is compatible, the console will display: DrvLoad: Successfully loaded [usbDriveLetter]:\[path_to_driver]\[driver_name].inf

Example:

DrvLoad: Successfully loaded C:\e1c6432.inf

• If the driver is not compatible, the console will display an error.

Note: The error may vary.

Example:

DrvLoad: Unable to load c:\BadDriver.inf (Error 0xe0000100)

• If manually attempting to use drvload.exe to load a driver fails, this must be corrected before OSD or Provisioning tasks can work.

Possible Causes of a Failure

• The test may have selected the wrong file.
• Dependent files may be missing that are needed as a reference by the *.inf file.
  • .dll, .cab, .sys files may be dependencies for the driver. Try adding them if available.
• The driver file added may be corrupted. Try re-downloading and testing.
• The driver selected may be incorrect. Try a different driver.
  • Windows Blue drivers have been seen to work in some circumstances where Windows 8.1 x86 drivers did not.

Initializing the network stack after installing NIC drivers

• It is a common requirement to add NIC drivers to the boot.wim image so WinPE is able to get an IP address and communicate on the network
• After loading a NIC driver successfully, you need to initialize the network stack so that it uses the driver and obtains an IP address
  • You can do this simply by running InitializeNetwork from the command line
