Install WinDbg
Download Windows 8.1 SDK from the SDK archive or via here
These instructions will use the default installation location for WinDbg:
C:\Program Files (x86)\Windows Kits\8.1\Debuggers\x86
Warning
The installer will likely complain it cannot find a WinDbg installation as it looks in an older location.
Just only need to change to the WinDbg’s installation location is fine.
-
Once installation is complete, you can tweak your Intel UDK configuration file further from this location:
C:\Program Files (x86)\Intel\Intel(R) UEFI Development Kit Debugger Tool\SoftDebugger.ini
-
Modify the configuration file as below:
