I currently have Pop!_OS 22.04 installed on an unencrypted ext4 partition. I want to set up a dual boot system where both Pop!_OS and Arch Linux use encrypted partitions.
Current setup:
- nvme0n1p1: 1GB boot partition
- nvme0n1p2: 650GB Pop!_OS (unencrypted ext4)
- nvme0n1p3: 4GB encrypted swap
- ~200GB unallocated space available
Goals:
- Convert my existing Pop!_OS to use LUKS encryption
- Install Arch Linux on the free space with encryption
- Set up GRUB to handle both encrypted systems
- Learn Hyprland on the Arch side while keeping Pop!_OS as daily driver
Questions:
- Can I encrypt an existing Pop!_OS installation in-place, or do I need to backup/restore?
- What's the best approach for dual boot with two separate encrypted partitions?
- How should GRUB be configured for this setup?
