I am trying to install Manjaro 18.0.4 with a specific storage configuration: an encrypted btrfs root partition and a plaintext ext4 boot partition on an SSD (sda) and encrypted btrfs home and swap partitions on a mechanical hard drive (sdb). I also have a small third partition on the SSD with the
bios-grub flag enabled which is where I assume the bios/efi boot data will be. I've tried both GPT and MBR partitions. I am using the manual partitioning feature on the
With these settings, the installation process manages to start and apply the changes to the disks, but at some point afterward the installer just goes back to the splash screen. At one point I got an error saying the grub installer exited with an error code but I can't reliably replicate this.
I am installing onto a virtualbox image at the moment to test the install process but I have it configured to have as similar a storage configuration to my target bare metal system as possible. I suspect the same problem will happen on bare metal.
What could be causing this, and how do I fix it so the installation can proceed?
