DS 7.5 SP1 HF5: UEFI booting

I have DS 7.5 SP1 HF5 working beautifully, and I image Windows 7 onto PCs with either the WinPE 4.0 automation folder or via a WinPE flash drive (created with bootwiz).

Due to the 2 TB boot volume limit, I'm started to have to set PCs (specifically, the Dell OptiPlex 9020) to use UEFI instead of legacy boot. So my questions are:

- How do I create a Preboot Configuration that supports UEFI?

- How to I create an ISO with bootwiz that supports UEFI?

Thanks!
