| 1 100MB EFI partition # Hex code ef00 | |
| 2 250MB Boot partition # Hex code 8300 | |
| 3 100% size partiton # (to be encrypted) Hex code 8300 | |

| # Mount the new system | |
| mount /dev/mapper/vg0-root /mnt # /mnt is the installed system | |

| In /etc/default/grub edit the line GRUB_CMDLINE_LINUX to GRUB_CMDLINE_LINUX="cryptdevice=/dev/sdX3:luks:allow-discards" then run: | |
