Win11 LTSC Failing to Install

I'm a noob to NTLite. I'm trying to update a Windows LTSC OS distribution for my company. But so far I have not been successful with creating an updated image from w/in NTLite. I'm using VirtualBox to test the OS install. I can create a VM w/int VirtualBox using the original Win11 LTSC ISO file. Then I tried to use the ISO from w/in NTLite. Even without making any changes to image, just creating a new ISO file, the ISO fails to install in VirtualBox. Basically I will get the "press any key to boot CD/DVD" but then it will go to the blue Recover screen. I have tried to click in the windows of the VM booting and hit a key right when this message is displayed but still it won't boot and just goes to Recovery.

1) Any suggestions of how I can successfully create a usable ISO to deploy a new VM?
2) Are there any step-by-step how-to guides that can walk me thru this process in NTLite. I've been looking at the guides and haven't found anything helpful yet.

I took that image created in my last message and I was able to install that onto an actual laptop. It just didn't work to a VirtualBox VM for some reason. That ISO image did not have any presets.

I since have gone back into NTLite and after loading the image, just went to Apply, provided an ISO name, and then hit Proceed to create the ISO. No other settings changed. I then tried to install that image to a laptop (not a VM) and the install failed. The install got as far as the blue screen saying that the install will cause the computer to reboot multiple times. At the first reboot I get a dialog window that says that the Windows 11 install failed. No other information. I'm including the auto-saved preset that goes with producing that ISO.

Your starting image is 26200.8737, is this a clean MVS image or something already updated/modified before you loaded it into NTLite?
 
Clean image from MS. I am able to install that image w/out touching NTLite. But when repackaged with NTLite it fails the install.
 
I figured out that my bios was too told and I needed to update it in order to get the 2023 keys for secure boot. That is done. But I do have secure boot turned off and its still failing. I did a google on the current error and this is the info I was returned:

the installer is still failing at the identical spot (Status = [c000000f] / Error: 0x80070002) because it cannot open the BCD template store. This happens when the Windows installation media itself has a corrupt template file, or the internal storage controller mode is hiding the target partition during the final assembly phase

I don't really know what this means. Was there something corrupted when NTLite created the ISO?
 
This sounds like a WinRE-related problem (?). You don't use an explicit disk layout in NTLite (it's optional). What happens if you perform a diskpart "clean / convert gpt" on the target drive before running the install?
 
Originally I was trying to define my partitions but now I'm keeping it simple. I currently don't have anything defined under unattended so I'm using the default disk layout. And I have been using diskpart as described but that hasn't helped yet.
 
As described earlier, I can install the original Win11 ISO. If I add in the ISO or extracted folder into NTLite and then just right-click and select Create ISO, that one also will install. But when I load the ISO and then just go to apply to create the ISO, that one fails everytime I try to install it.

I do see the BCD template error:
Code:

What's surprising is your EFI volume is on HarddiskVolume6, which is a higher than normal volume number. Typically the EFI is on HarddiskVolume1. Is this a single disk setup?
 
I did not add any disk setup under the unattended section so just assumed there is a default set up. I did clean the target partition so nothing is there. Not sure what you mean by "a single disk setup". The target only has one disk and the ISO is extracted to a USB drive using Rufus.

I am new to NTLite so maybe there is something I'm missing. Just struggling to get a successful install before adding in more stuff (disk partitioning, extra apps, registry items, etc.)
