Troubleshooting SCCM Part VII .......... OSD .... Part II
Part II : From windows PE to Full Blown OS
Once the client boots to PXE (which we have explained in Part I ) the clients goes to the management point and get the list of policy.
If any Mandatory (required) deployment then it will go ahead with that else if it is available deployment it will show you the List of advertisement.
From the WindowsPE and before HDD format the sequence of events is logged in SMSTS.log in the location x:\windows\temp\smstslog\smsts.log
The snippet below shows which policy are retrieved which policy is downloaded and from where. SMSTS.log are usually pretty big.
I will be pointing only the required lines rest I will attach in a ZIP file which you can look in detail.

It will then check for all the content location for reference package you would find multiple occurrence of location request as below related to content reply .
If any issues with content lookup the TS would fail here and in such situations you would need to check the packages\application\boot images\OS image etc is distributed the DP which the client is assigned to.

Till this time TSPxe will be component in questions and once this is completed the Tasksequence is then read and parsed.
Then the Tasksequence starts performing one by one. Here on TSMager component will come in to action. This is the TS I have used which is a very basic one

If you filter with Successfully completed the action you can get which all completed and if any steps fails you could check the error accordingly and then troubleshoot.
Each step does different things to know in detail please check the article https://technet.microsoft.com/en-us/library/hh846237.aspx

Once these steps are completed the windows PE phase get finished and it will boot to OS which we had applied
Save the current environment block TSManager 20-09-2013 19:20:41 732 (0x02DC)
Expand a string: %_SMSTSMDataPath%\Logs TSManager 20-09-2013 19:20:41 732 (0x02DC)
Current operating system is Windows PE. Computer will automatically rebooted when the process exits. TSManager 20-09-2013 19:21:11 732 (0x02DC)
The action (Setup Windows and Configuration Manager) initiated a reboot request TSManager 20-09-2013 19:21:11 732 (0x02DC)
You will also find the information from windows PE load to format of the disk in the SMSTS.log located at x:\smstslog\smsts.log.
Now since we have drive created and OS applied c:\_SMSTaskSequence\ which will be used as a working directory for the Tasksequence and once it is completed this will be deleted. Presence of this folder after the Tasksequence itself is a indication that TS did not complete fine.
In the windowsPE phase what ever you have in X:\ drive smsts.log will also be there in c:\_SMSTaskSequence\Logs\Smstslog\smsts.log.
Once the system boot to complete OS the X:\ data will no longer be available so you would need to grab logs before the reboot.
You can use this https://blogs.technet.com/b/sudheesn/archive/2010/03/09/how-to-get-the-related-logs-for-troubleshooting-operating-system-deployment.aspx For 2012 only the change is the location in boot image properties rest everything is the same.
Now once the system boots to full OS it will configure the OS, drivers and then install the client. In winpe only download happens till the client is installed you will find the logs in c:\_SMSTaskSequence\Logs\Smstslog\smsts.log and then it will continue through the Tasksequence if any further steps are there.
Once the client is installed then you will find the logs in the :\windows\ccm\logs\smsts.log in 2012 and in 2007 :\windows\system32\ccm\logs\smsts.log :\windows\sysWOW64\ccm\logs\smsts.log
As you can make TS of your choice and the failure can happen any where in this it is difficult to explain all possible issues. But if you can read the smsts.log most of the issue can be sorted out as failure of any step is given in detail in the logs. What is important is that you need to find the first step failed as in many cases I had seen people looking at the last error and get misled.
For OSD issues observation , probing and finding the first major failure is the key. Just what we need to understand that when these basic steps are in place then it is just how the Tasksequence was created can make issues. In various to isolate the issue different trial and error method like disabling few steps or deleting few will make a lot of sense.
If you think TS as a step by step command thrower and approach the issues things will be simpler. If you have failure when OS is being applied , driver injection etc the other OS logs will be of help.
This link has a good collection https://technet.microsoft.com/en-us/library/dd744583(v=ws.10).aspx
I am also attaching a ZIP file with the logs which was collected while preparing this doc. For more details you can refer this.
Hope this helps
