Question
Tuesday, August 5, 2014 4:46 PM
Hi,
We're running SCCM 2012 R2 CU2. Our boot images have Enable command support enabled. I am able to use F8 to get a command window at the Welcome to the Task Sequence Wizard. After the first restart, F8 and Shift-F10 have no effect.
I have a computer that keeps getting hung somewhere in the task sequence but I have no way to get to the logs. If I force power off and power on again, the computer is stuck in the same place again with no command window support. I tried booting to WinPE and use CMTrace but it cannot access the OS drive from the "in-progress" deployment which I believe could be due to drive encryption.
How do I get the command prompt (F8) to work? I have done some searching and haven't found a solid answer yet.
Thanks,
Rob

You've confirmed that F8 works to open a command prompt in the initial WinPE, but not after the next part, which is an indication that the task sequence switches to using a boot image that doesn't have command prompt enabled. Although you may have already done this, confirm that the boot image used by the task sequence does indeed have command prompt support enabled.
If all of your boot images do have command prompt support enabled (which, you should be using only one if at all possible), try disabling and re-enabling the support, and confirm that the process finishes correctly.
F8 will work throughout the entire task sequence, if enabled properly.

F8 only works from Windows PE. I'm asuming that you're no longer in Windows PE after the first reboot?

F8 only works from Windows PE.
I've seen it also working when already in the target OS while the TS is still running. In fact most times it does, but sometimes it doesn't. I have no idea why.

After the first restart, the task sequence is still running and I thought F8 was available as long as the OS is still being deployed. I could swear that SCCM 2007 could launch a command window at any point during the image deployment.
I cannot get to this failing computer's logs so I can get some info on what is failing.

The OSD Deployment Status reports may be of some use to you here though I know its not the solution you are asking for.

I concur with Torsten - I have used F8 numerous times when in the OS but I haven´t really researched it further.
I know that this does not answer you question but you could implement this solution into your task sequence so the logs are copied to a file share if the Task Sequence Execution fails.

The deployment is getting hung, it never actually stops/fails. I've seen it stop in a couple of different places. We do have steps similar to the link you gave but since the deployment doesn't actually stop, logs are not being copied.

Are you sure that you don't need a Fn+F8 to get it to work, I ran into this problem using our MS Surfaces
Are you using PXE to boot into WinPE or Boot Media?
Is your boot environment and task sequence both using the same boot image? You might have command support on one boot image and not the other.

I'm using a standard keyboard so F8 should be all I need. Because of SCCM 2012's design, we will not be using PXE. I am using the boot image on a flash drive and I have made sure that the boot flash drive matches the boot image the task sequence uses.
I know what you mean about the Surface. I noticed that as well.

I've found that if the task sequence progress window is not visible, then the F8 key will not launch the command prompt. I'm assuming this is due to the task sequence engine not being loaded fully. It may be stuck or just waiting to complete.

Old post i know but thought I would add this for anyone coming to view. The reason it never completes and just hangs is because the F8 command window is running it just isn't visible in the shell. I have this same issue, tapping F8 nothing happens but when a restart computer step processes it just sits there "Setup is preparing your computer for first use".
Usually a hard reset works here and the TS picks up where it left off.
This doesn't explain why the F8 command prompt window is not visible in the shell. I should also mention that before the password is entered the F8 command works well and it works well right up until the point that it leaves PE and goes into the real OS.
Maybe someone else can shed some light on whats going on. So far I am deploying these task sequences to VM's that are sat on ESXI 5.5. Never personally had an issue with this on real hardware but a colleague of mine has.
Strange and frustrating one.

I just ran into this behavior when trying to do some Win7 OSD, but it only started happening to us after we upgraded to SCCM 2012 R2 SP1. After the reboot from the Install OS group tasks, if I press f8 at the right time I can very briefly see the command window pop-up when I press F8 and then it goes to the background layers behind the gray system center desktop background (which only just started appearing during OSD after the SP1 update). I know it is still running back there because if the task sequence errors out it won't restart the machine while the command window is open. I also have another thread on my mouse cursor disappearing at the exact same point when trying to do Win 8.1 OSD, so there must be something with the visible layers when the system reboots to the full OS to continue the task sequence for setting up the OS and installing applications.
Pressing Alt-Tab does nothing. Is there a way to stop the SCCM gray background from appearing on reboot?

I have had this problem for a while too, with 2012 R2 SP1.
It turns out (at least in my case) to be linked to the BIOS mode of the PC. If I stage the PC in Legacy Bios mode F8 stops working once Windows is running.
If the PC is staged in UEFI mode (or Hybrid) then the F8 console works as expected.
Maybe Microsoft have already phased out legacy bios support, but forgot to tell anyone... :-)

I cant understand why it would have something to with BIOS or UEFI. Curious though. What ND_CSIT says is exactly what I have seen.
Interestingly I was running some OSD earlier this week and the f8 was working post PE. It seems to be more of an issue when deploying Windows 8 than Windows 7 or at least that's how we have experienced it.

I guess I WAS playing around with one of our newer Dell desktops at the time trying to get the deployment working in UEFI only mode. It ended up being too much of an annoyance with various settings needed so I switched back to legacy only. I didn't pay attention to exactly when it started working again, but F8 has definitely been working (post-WinPE) ever since I gave up on UEFI for a Win7 machine.

In the new OS, F8 will show the command-prompt if the OS is Windows 7. The command-prompt will not show-up if the OS is Windows 8 or Windows 10. Quite confusing indeed, as some are seeing that it works, while others are seeing that it does not work - it all depends on the version of Windows.
The task sequence engine actually launches the command-prompt. However, changes to Windows are preventing the command-prompt from being visible. So, the command-prompt is there, but you just can't see it.
In the future releases of SCCM, this should already be addressed.
Tuesday, November 3, 2015 8:22 PM
Yup, since the SP1 install for 2012 r2 we are having no problem seeing the command window now with win8 or win10 whether it is UEFI or not.
Though we are having a problem with the mouse cursor disappearing.... that is in another thread.

I was having this issue. Simply disabling and re-enabling Command Support in the boot image fixed things.
