After some more research, I think I found the definitive answer to the problem. It's a little bit more complicated. UEFI -> GPT BIOS -> MBR BIOS with disk > 2^32 sectores (2 TiB) -> GPT And searching for this, I stumbled over docs.centos.org, whose existence I ignored. Must be relatively new: https://docs.centos.org/en-US/centos/install-guide/StorageSpoke-x86/ See section "MBR and GPT considerations".
