# Install Arch Linux

Install Arch Linux is thing I always want to do for my laptop/PC since I had my laptop in ninth grade.

This is not a guide for everyone, this is just save for myself in a future and for anyone who want to taste a bit.

Assume your laptop/PC is UEFI-capable.

## [Installation guide](https://wiki.archlinux.org/index.php/Installation_guide)

Check disks carefully:

```sh
lsblk
```

[USB flash installation medium](https://wiki.archlinux.org/index.php/USB_flash_installation_medium)

### Connect to the internet

Read [iwd/iwctl](Applications/System/iwd.md).

### Partition the disks

Partition:

```sh
cfdisk
```

| Mount point | Partition type       | Suggested size |
| ----------- | -------------------- | -------------- |
| `/mnt/efi`  | EFI system partition | 512 MiB        |
| `/mnt/boot` | Linux extended boot  | 1 GiB          |
| `/mnt`      | Linux                | 24 GiB         |
| `/mnt/var`  | Linux                | 24 GiB         |
| `/mnt/home` | Linux                |                |

Format:

```sh
# /efi, /boot
mkfs.fat -F32 /dev/sdxY

# /, /var, /home
mkfs.ext4 /dev/sdxY
```

Mount:

```sh
# /
mount /dev/sdxY /mnt

# /efi
mkdir -p /mnt/efi
mount /dev/sdxY /mnt/efi

# /boot
mkdir -p /mnt/boot
mount /dev/sdxY /mnt/boot

# /var
mkdir -p /mnt/var
mount /dev/sdxY /mnt/var

# /home
mkdir -p /mnt/home
mount /dev/sdxY /mnt/home
```
