# 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

mkdir -p /mnt/var
mount /dev/sdxY /mnt/var
# /home
mkdir -p /mnt/home
mount /dev/sdxY /mnt/home
```
### Installation
```sh
pacstrap /mnt base base-devel linux linux-lts linux-zen linux-firmware neovim
# AMD
