Thanks for BIOS info, but . . . I cannot enable Legacy Boot (and I cannot disable UEFI).
I have a recent BIOS:
BIOS FNCML357.0050.2021.0303.2141 03/03/2021
Not sure whether I’ve missed something,
Well, it seems I am not the only one: NUC10 - can’t enable Legacy Boot ??
BTW, my NUC8i7HVK worked fine with UEFI (and Secure Boot disabled for Qubes-OS).
