SCCM Task Sequence reboots before Password entry

[T_Lister]

Good morning forum,

 

I have just upgraded my SCCM to 1902, I have installed the latest ADK, I've installed the latest PE and then I updated my boot image. What I cannot understand is that when I PXE boot a new client, it almost makes it to the Enter Password and then the client reboots. I've tried three different models of machine and I get the exact same problem.

 

Any advise would be most welcome.

 

Thanks in advance!

Last time I had this, it turned out to be a bad network driver in the PE image.

Aye, as above, or on the similar lines if you have any custom drivers in your boot you may need to re-add them if it regenerated the image rather than updating it (As in when confmgr auto pulls the ADK over the old ones)

Sorry to play the dull card.

Not all my devices had a network drivers in SCCM before. By that then I presume I was lucky they were even booting? However at least one of the devices I use does. Are you suggesting I removed the drivers from the boot image and then re-add them. Or do I need to do something else with my boot image? I've already run Update Distribution Point. That was the point in which it stopped working. Also taking into account that these don't have specific Windows 10 drivers I can download.

Do you mean drivers within your OS build? or for the Boot image?

 

The drivers for the Boot image are just for the PE environment, which as you said often isn't needed, but depends on the hardware. However, sometimes during the updating the Boot image gets deleted/re-made so it'll lose those drivers.

 

If you check your boot image (drivers tab) does it have any drivers currently attached? If so which ones? (Again just the boot image, not the OS)

There are some network drivers in there. I have since managed to pull the logs. Done it on two devices and they're the error. Attached.

Hi Trenton,

 

In your task sequence, in the "Apply Operating System" step, do you specify the logical drive letter that you want to apply the OS to?

 

Thanks,

Looks as if it's not detecting a HDD at all.

[T_Lister]

Doesn't get as far as the task sequence. Basically it was running SCCM 1810 with no problems. I updated to 1902 and now I cannot get to my password screen to even pick a task sequence. I set up a VM yesterday afternoon and booted to that. Exact same problem but without the red error entries. And as you say, it looks like it's no longer seeing an HDD...

Are there any disks listed if you run DISKPART?

[T_Lister]

I've cleaned out all the drivers from the Boot Image (x64) image and updated the Distribution Point again. Seems to have done the trick. At the very least I can image, although whether they error out is yet to be seen. Step in the right direction at least.

Have you enabled F8, and checked out the smsts.log in X:\Windows\Temp\SMSTS\SMSTS.log

 

I had to do it yesterday - turned out the machine had a bad bios battery and had wrong time/date info.
