    I've been beating my head on this BIOS for two days now and I'm prepared to say that this system is not UEFI compatible. There is an option to use the UEFI boot in BIOS, but you cannot use it unless you enable the Legacy Boot option.

    If you enable the Legacy option, it will not use the UEFI version of the BIOS, and will install Windows with an MBR partition, regardless of how you prepare or format your target drive.

    I'd love to be proven wrong, but I have tried every version of the BIOS that Dell published (except A04 & A06). Not one of them will allow an OS to be installed with GPT, so that means no UEFI.
