So, Legacy BIOS can be used to install operating systems, on the same "hard drive", that has a UEFI installed operating system, and, that has an EFI partition. That is, on computers that have Legacy BIOS available.
Not playing Monty Python with you :) and I think this is an important thing to you, When you booted up to a linux OS that you think is legacy-bios, verify if indeed it is by the following command in the terminal test -d /sys/firmware/efi && echo UEFI || echo BIOS If output is "UEFI", you are booted in uefi, There is nothing wrong as I too have booted legacy-bios OS from a uefi grub. The problem arises when we do a 'grub-install' like when there is a new version of grub to update. The system will then install to the UEFI version of GRUB and use your ‘0xEF02’ partition as the efi partition. I think this is what happened in your case. Cheers.
