2.3.2 Configure Debug

There are several possible debug targets in a Windows set up. To cover them all, open an elevated command prompt window on the target system, and enter the following commands: 

> BCDEDIT /SET '{BOOTMGR}' BOOTDEBUG ON
> BCDEDIT /SET BOOTDEBUG ON
> BCDEDIT /SET DEBUG ON

Note: When boot debug is enabled, Windows will wait for a while during the boot to see if a WinDbg is connecting, and then proceed with the boot. Thus, enabling boot debug will make the boot take a little longer (a few virtual minutes of wait time).
