User:Soloturn/Quick Installation guide UEFI

This installation guide installs Arch Linux on a System with three partitions EFI, root, and home. Dual boot with windows 10 is possible, as well install on a USB disk or memory stick. No legacy technologies are considered, please use Installation Guide in such a case.

Format disk and mount partitions

Best do it with GParted and create the following partitions or make sure they exist:

• the partition table is GPT
• the EFI partition is FAT32, around 250MB
• the root partition is ext4, around 35GB
• the home partition is ext4, rest of the disk

rEFInd is used to find existing kernels resp operating systems to boot. reuse the existing EFI partition created by microsoft windows is possible. mount the root partition and the EFI partition into it.

mount /dev/sda5 /mnt
mkdir /mnt/esp
mount /dev/sda3 /mnt/esp

Install Arch

a user is created which is "archie"

export myuser=archie
export myhostname=hostn
pacstrap /mnt base
genfstab -U /mnt >> /mnt/etc/fstab

exit

# install same packages as existing arch system
pacman -S --needed - < /home/${myuser}/.config/pkglist-abs.txt

# swap

# this is for android
groupadd android-sdk
gpasswd -a $myuser android-sdk
mkdir /opt/android-sdk
setfacl -m g:android-sdk:rwx /opt/android-sdk
setfacl -d -m g:android-sdk:rwX /opt/android-sdk

exit

reboot and configure

install yay AUR helper

AUR make is not allowed as root, so become your user to clone and compile. after yay is installed, install the other AUR packages:

cd /tmp
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si
yay -S --needed - < /home/${myuser}/.config/pkglist-aur.txt

store pkglist to later install same packages from existing arch installation

become your user, check and update the package lists from repo if necessary

cd
pacman -Qqen > ~/.config/pkglist-abs.txt
pacman -Qqem > ~/.config/pkglist-aur.txt
git diff

if windows is installed

If windows is installed it might take precedence, so add an entry for the UEFI partitions rEFInd boot loader and set it after the USB device boot as second option. in the order just take the last number listed by efibootmgr:

# efibootmgr
# efibootmgr -v
# efibootmgr --create --disk /dev/sda --part 3 --loader /EFI/Boot/bootx64.efi --label "rEFInd local boot"
# efibootmgr -o 0,4,1

in case the bios does not let the order change via efibootmgr, go to the bios and alter the boot order there.

miscellaneous

set network config for netctl, show week number, activate network time protocol

# wifi-menu
$ gsettings set org.gnome.desktop.interface clock-show-date true 
$ gsettings set org.gnome.desktop.calendar show-weekdate true
$ timedatectl set-ntp true

maintain

upgrade, delete everything not installed from package cache, delete orphans

$ yay -Syu
$ yay -Sc
$ yay -Rsn $(pacman -Qdtq)
# pacman-key --populate archlinux
