1. Check whether the motherboard is in UEFI mode

ls /sys/firmware/efi/efivars

1. Connect network

dhcpcd

1. Test whether the connection is successful

ping baidu.com

1. Ensure that the system time is accurate

timedatectl set-ntp true

1. View hard disk partitions

fdisk -l

1. Hard disk partition
   Partition using cfdisk tool

cfdisk /dev/sda

• After entering the tool, select gpt
• Partition recommendation
  EFI file system 512M
  linux swap greater than 512M
  Space left in root directory
  EFI partition type (Tye) select the first EFI System
  linux swap partition type (Tye) select linux swap
  The root partition type (Tye) is linux filesystem
• When the partition is completed, select Write. Here, you must enter yes and Quit
• Check the partition again

fdisk -l

• Format partition:

EFI partition format is f32

mkfs.fat -F32 /dev/sda1

The partition format of linux filesystem is ext4

mkfs.ext4 /dev/sda3

• swap partition settings

Swap space initialization

mkswap /dev/sda2

Enable swap space

swapon /dev/sda2

1. Mount file

• Root directory file (linux filesystem)

mount /dev/sda3 /mnt

• Create additional mount points to the appropriate partition

mkdir /mnt/boot

Create the boot file in the root directory and hang it in sda1 (that is, hang the EFI file in sda1)

mount /dev/sda1 /mnt/boot

1. Modify domestic image

vim /etc/pacman.d/mirrorlist

Two domestic images are recommended here

http://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch
http://mirrors.aliyum.com/archlinux/$repo/os/$arch

1. Install the basic software package, linux kernel and firmware of conventional hardware

pacstrap /mnt base base-devel linux linux-firmware vim dhcpcd

1. Generate fstab file

genfstab -U /mnt >> /mnt/etc/fstab

1. change root to the new system

arch-chroot /mnt

1. Set time zone

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

1. Synchronization time

hwclock --systohc

1. localization

vim /etc/locale.gen

Remove the comments from the desired area

en_US.UTF-8 UTF-8
zh_CN.UTF-8 UTF-8

Generate locale information

locale-gen

Create locale.conf and edit it

vim /etc/locale.conf

input

LANG=en_US.UTF-8

Setting Chinese is not recommended here, which will cause TTY garbled code
15. Create the hostname file and add the hostname

echo "host name" >> /etc/hostname

Add information to hosts

127.0.0.1 localhost
::1 localhost
127.0.1.1 host name.localdomain host name

1. Set root password

passwd

1. Install motherboard microcode (for intel users only)

intel processor user installation

pacman -S intel-ucode

1. The hard disk has dual systems that need to be installed (only arch does not need to be installed)

pacman -S os-prober

1. Install startup management tools

pacman -S grub efibootmgr

Generate GRUB EFI

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB

1. Generate startup file

grub-mkconfig -o /boot/grub/grub.cfg

1. Notebooks need to be installed

pacman -S iw wpa_supplicant dialog netctl

1. Turn on the network

systemctl enable dhcpcd

1. Start network

systemctl start dhcpcd

1. Exit installation

exit

perhaps

Ctrl+D

1. Manually unmount the mounted partition

umount -R /mnt

1. reboot after installation
2. Create a sudo user

useradd -m user name

1. Set user password

Start the display manager and network manager services after installation

systemctl enable sddm.service

systemctl enable NetworkManager.service 

1. Restart the computer after installation
