I followed this tutorial from 2014: https://www.oxygenimpaired.com/multiple-linux-distro-installs-on-a-luks-encrypted-harddrive

I am installing Linux Mint 19.1 XFCE and Ubuntu 18.04, both fully encrypted in a single disk. First I installed Linux Mint on /dev/sda5.

After following all steps to install the first Linux, and rebooting the machine, I got into the Boot drops to a (initramfs) prompts/busybox with this error:

When following the tutorial, I ran the following commands:

  1. fdisk /dev/sda, then, created the following partitions:

  2. cryptsetup luksFormat /dev/sda5
  3. cryptsetup luksOpen /dev/sda5 sda5_crypt
  4. pvcreate /dev/mapper/sda5_crypt
  5. vgcreate vggroup /dev/mapper/sda5_crypt
  6. lvcreate -L1G -n mint_xfce_swap vggroup
  7. lvcreate -L8.9G -n mint_xfce_root vggroup
