The UEFI partition should only be created on devices where UEFI is detected, and where the UEFI partition is needed. If you don't want/need this, you can set UEFI back to Legacy in the BIOS of your device. If the UEFI is incorrectly detected you should report this is a bug.
I have changed the UEFI/Legacy Boot BIOS settings to Legacy Only instead of 'Both & Legacy Only' and I have created Provisioning Boot Media via LDMS 9.6, however, when it boots into WINPE it still boots into UEFI mode not Legacy mode.
I have tried following WinPE: Boot in UEFI or legacy BIOS mode with no luck.
Any idea ?
