All I search for this says, makes me understand that GPT is related to UEFI, but is it possible to install using GPT disk format, in a 32 bit system using bios (not legacy mode)? I tried installing Arch in a VM simulating 32bit and using a partition like:
-BBP /boot / /home swap
and it did not work. Is it possible? If it is, is that the correct partitioning using BBP? Maybe it's cause I tried encrypting the / and /home without using LVM following the Arch guide, but i'm not sure.
