When I install Manjaro (16.10.3) from the LiveCD using the erase drive + encrypted option, it seems to create a setup like the following:
/dev/sda2used as swap
- Unknown process prompts for decryption passphrase at boot
- Entering passphrase brings up GRUB menu, from which Manjaro can be booted
How is this accomplished? On the Arch wiki's "encrypted boot" section, I can only find a description for UEFI systems (my computer is BIOS only). That one also involves creating a separate (encrypted)
/boot partition, which Manjaro does not create.
