Arch linux install guide (Installing bootloader and luks on usb key).

INFO

USB KEY = /dev/sdc SSD = /dev/sda

Partition usb memory and create filesystem

# GPT it
parted --script --align optimal /dev/sdc mklabel gpt
# Create boot-partition
parted --script /dev/sdc mkpart ESP fat32 1M 513M
# Set boot-flag
parted /dev/sdc set 1 boot on

mkfs.vfat -F32 /dev/sdc1

Setup encryption on SSD

# Greate header "Disk"
truncate -s 2M header.img

#Whipe the disk, select a password
cryptsetup luksFormat /dev/sda --header header.img

#Mount disk
cryptsetup open --header header.img --type luks /dev/sda enc

## Setup lvm and partitions on SSD
pvcreate /dev/mapper/enc
vgcreate MyStorage /dev/mapper/enc

lvcreate -L 8G MyStorage -n swapvol
lvcreate -l +100%FREE MyStorage -n rootvol

mkfs.btrfs /dev/mapper/MyStorage-rootvol
mkswap /dev/mapper/MyStorage-swapvol

Mount partitions

mount /dev/mapper/MyStorage-rootvol /mnt
mkdir /mnt/boot
mount /dev/sdc1 /mnt/boot
