Dell Command|Configure bootable devices with UEFI

Hello,

We will shortly be migrating to Windows 10.  The third-party company who are putting together the build on a new installation of SCCM have recommended that we switch to UEFI with Secure Boot switched on.  To this end I have been trying to come up with a series of CCTK tasks which set the options we need. This will be added to the task sequence.

Essentially, what we want to do is the following:

• Regardless of the Dell model, update the BIOS to the latest version and, at the same time, reset all settings back to the factory defaults. This we can do already using standard switches for the BIOS update packages.
• Using CCTK switch over to UEFI with Secure Boot and allow booting from USB and PXE.

The series of steps I have so far looks like this:-

1. InstallHAPI
2. cctk.exe bootorder --bootlisttype=uefi --sequence=hdd,usbdev,cdrom,embnic --enabledevice=hdd,usbdev,cdrom,embnic
3. cctk.exe --legacyorom=disable
4. cctk.exe --secureboot=enable
5. cctk.exe --wakeonlan
6. cctk.exe --wakeonlan=enable
7. cctk.exe --uefinwstack=enable
8. cctk.exe --embsataraid=ahci
9. cctk.exe --forcepxeonnextboot=disable

However, although most of the settings work, after running these steps the only options available in the F12 boot menu are the Onboard NIC (IPv4) and Onboard NIC (IPv6).  The option to boot from USB is, for example missing.

In effect I want to, more-or-less, reproduce the items that appear in the "Legacy" boot menu in the UEFI equivalent.

Is this all possible?  What I am missing here?

Any assistance would be appreciated.

Regards,

Stephen.
