Even before installing the second system, simply doing a manual partitioning results in an odd partition table. The partition table generated when selecting 'use the entire disk' puts the GPT partition at the beginning. This shows up in gparted as the bios_grub partition. When I manually partition and create one swap and one ext4 root partition, I'd figure the GPT partition would go at the end. Both fdisk and sfdisk show sda1 as being a GPT partition, however. And gparted doesn't see any bios_grub partition at all. Somehow the system boots but it seems that the partition table is inconsistent. That might explain why later resizing partitions to install another system fails. I'm attaching the logs from a single installation using manual partitioning.
