OSD Task Sequence fails to install SCCM client

Question

Hello,
Our OSD task sequence fails to install the SCCM client with certain images.
The TS gets to the "Setup Windows and Configuration" step, during which it downloads all the necessary SCCM client files (silverlight, C++ redistributable, client.msi....etc.). At this point computer restarts and in never loads back into the
task sequence, instead it enters the minisetup (setup is starting services, setup is installing devices, setup is applying system settings...preparing computer for first use), after which the computer restarts and you are back at the CTR+ALT+Del screen.
The computer has joined the domain and has run all other steps but it has failed to install SCCM client. I can also see the leftovers of an incomplete TS under c:\_SMSTaskSequence
If we change the image specified under "Apply Operating System" step, everything works ok.
It appears there is something wrong with this particular image. Any ideas?
Logs show no errors. Let me know which logs you'd like me to post (and from which location)
There is no ccm folder under c:\windows

Hoping you are using ConfigMgr 2012 R2. If a client machine Join to Domain and doesn't proceed with other steps and not installing the CCM client, then problem seems to be with the Image.Do you have any RunOnce registry setting specified in the Image? You
can mount the Image and check those settings.
RunOnce Key Reference :

If the above key is present in the Image, TS Engine won't resume after the reboot.
You need to use a new variable "SMSTSPostAction" at the end of the Task Sequence, to add your custom actions.
The above variable is applicable in CM 2012 SP1 and R2.
