Imaging disk to GPT and BIOS configuration modification happen in one session.
I actually want configuration change to happen during restart.
So...
Boot BIOS mode
Format disk to GPT and UEFI boot
Reconfigure BIOS with BCU
Reboot - I'm expecting UEFI Secure Boot to take effect and boot to first hard disk and continue TS. Disks not checked for UEFI boot files, can only continue to PXE
I want system to boot to GPT disk so TS can continue uninterrupted for technicians.
