Device drivers installation via Unattend.xml

Hi,

The log file location will depend on the point of when the installed failed:

Before the installation starts in WinPE Pass – x:\windows\panther – WinPE only - Use Shift+F10 to open command window and run notepad.exe

After installation starts – c:$Windows.~BT\Sources\panther - Use Shift+F10 to open command window and run notepad.exe

After installation is completed – c:\windows\panther

Log files to review:

Setupact.log – master log file for the whole installation process.

Setuperr.log – smaller version of Setupact.log, but only includes the errors. This should be the first log to look at.

Cbs_unattend.log - this log records the package setup and answer file processing.

Or what is the "other" procedure to install drivers via unattend.xml file?

We could also follow the official method of installing drivers through a UNC path.

@XinGuo-MSFT Thanks for your reply. My answer file is exactly as you provided with the difference to have a local path.
Setuperr.log & Setupact.log have been reviewed already, and nothing suspicious was found. Cbs_unattend.log >> What is the location of this file?

Before the installation starts in WinPE Pass – x:\windows\panther – WinPE only - Use Shift+F10 to open command window and run notepad.exe >> How interesting .... Once the image is deployed, and PC is turned on for the first time, will the setup create a temp PE location "X:"?
