Microsoft deployment toolkit logs and task sequencer logs

Each MDT script creates its own individual log file during execution. These log files normally match the script name (for example, ZTIGather.log, ZTIDiskpart.log, and so on) or begin with the script name (for example, ZTIConfigureDHCP_DISM.log).

The information written to both log files is the same; so normally, it is okay to just take a look at the aggregated BDD.log as it contains everything needed.

The position of BDD.log and individual script logs changes several times during the deployment process. During the Windows PE phase, when there is no partition accessible/existing, the log file will be hosted under X:\MININT\SMSOSD\OSDLOGS ...
