BIOS-systems can't read GPT partition tables, only MBR (thus the warning), but MBR can't have partitions larger than 2 Tb. There is an workaround to make a small partition for the bootloader and make partition table a hybrid MBR/GPT one. This way BIOS has access to the bootloader as an MBR partition and bootloader has access to everything else normally — as GPT partitions.

You make like a 1MB BIOS boot partition at the start of the disk.
And it get ever more complicated after you do things like RAID.

That work around is the thing I was referring to.
I had to convert an Ubuntu 18.04 preseed to accept GPT while using BIOS. The easier way is to just use EFI, but there isn't really a benefit to EFI that I could convice my company to switch to it since BIOS just works.
