Based on https://gist.githubusercontent.com/heppu/6e58b7a174803bc4c43da99642b6094b/raw/96b7ab0ea6356ac783fe4c90d1cb7073bdbb107f/ARCH_INSTALL.MD

# Create bootable USB

Download iso and use Etcher

# Boot from USB and set prepare system

```bash
timedatectl set-ntp true
```

# Connect to wifi if on a laptop

```bash
wifi-menu
```

# Partition the disk

We will create 2 partitions, one for boot partition and one for LUKS encrypted partition

```bash
fdisk /dev/sda
```

```
* g
* n
* 1
* enter
* +1G
* t
* 1
* n

# Format, encrypt and mount partitions

I will create only swap and root partitions, but here you can create home, var and other partitions if you wish.

```bash
mkfs.vfat -F32 /dev/nvme0n1p1

cryptsetup -v luksFormat /dev/nvme0n1p2
cryptsetup luksOpen /dev/nvme0n1p2 luks

pvcreate /dev/mapper/luks
vgcreate vg0 /dev/mapper/luks
lvcreate -l +100%FREE vg0 -n root

mkfs.ext4 /dev/mapper/vg0-root

mount /dev/mapper/vg0-root /mnt

mkdir /mnt/boot
mount /dev/nvme0n1p1 /mnt/boot
```

# Install base system

```bash
pacstrap /mnt base base-devel
```

# Generate fstab

```bash
genfstab -pU /mnt >> /mnt/etc/fstab

cat /mnt/etc/fstab
# 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>
# /dev/mapper/vg0-root

```
Change relatime on all non-boot partitions to noatime.

# chroot into new system and prepare it

```bash
arch-chroot /mnt
hwclock --systohc

echo <your-hostname> > /etc/hostname

pacman -S dialog wpa_supplicant

passwd
useradd -m -G wheel <username>
passwd <username>

```
# Set locales

Uncomment en_US in /etc/locale.gen
