I’m having quite the strange issue here, and I’m unsure if it is model related, or simply Windows 10. For some background I have setup FOG and am using it to deploy out EFI images of Windows 10 for many systems. We have a couple of sysprep’ed images that have worked with dissimilar hardware before since there are 0 drivers installed on these images. We got 20 of these Dell Optiplex AIO 5270’s in for our clients and were attempting to image them. It became clear that the following changes were needed before we could deploy our images:
- Disable secure boot
- Change the SATA mode from RAID to ACHI (since RAID caused the drive not to be found withing FOG)
- Enable the UEFI networking stack (to allow for PXE boot to be enabled)
And that was about it. We have been able to deploy the image out, however, every time we do, upon reboot there is no “Windows Boot Manager” option to boot from. The only thing that I could think of that may be different from these models is the presence of a TPM chip. We disabled that and attempted to re-deploy with no luck. The other thing we attempted was to capture the image using a non-resizable method as I’ve read that with Windows 10 it can be a bit hit or miss using the resizable option. This also did not change the outcome. Once again, these images and methods have worked on several other computers (makes and models). Any help or insight into what can be done would be a great help. Thanks in advance.
