Today I accidentally deleted my primary osx partition from my very old macbook air 4,2 (2011) with last installed os was el capitan. From the beginning I just want to give my macbook some extra space but it turns out cleaning all the HDD …LOL, I seriously don’t know how in the hell this could happened, this is a lesson for not to clean your HDD in the middle of the night.
And then I follow up the step from apple website on how to reinstall osx, turns out that I have to download 10Gb update including el capitan.
Whaaa whaa whaaaaattttt!!!
Without a doubt I immediately cancel the download, had crossed my mind to get a linux os. So many distro can be installed, googled around and I found that Archlinux is a better option because of its crowded community, simplicity and support for many file systems. And also I like how archlinux define simplicity,
without unnecessary additions or modifications
much more customable by your needs, imagine it as a one big playground of LEGO blocks for operating system. You only need a 500Mb Archlinux Iso to get this done, Compare with 10Gb download and an endless waiting.
I’d like to share my experience starting from installing Archlinux and get started with Archlinux, me myself is not a linux power user, I do a lot of googling to get through the installaion, so here I’ll explain all of my finding.
Get the ISO forget the Archboot
I’d like to have something such as ubuntu light GUI that will guide you through the installation step, so then I found Archboot, been trying to install Archlinux from Archboot usb bootdisk several times with no luck so its just wasting my time, it seems this archboot iso is outdated, I gave up. It would be better if you could just use the iso that you can download here https://www.archlinux.org/download/
Boot to Arch ISO
- Download the iso flash it to your usb disk with dd command or any software, check this great post of raspberrypi installation for reference.
- You may need a usb-ethernet dongle to connect with the internet, or some people using their cellphone internet tether through usb cable.
Plug in your USB bootdisk and hold ‘alt/option’ button while your system boots up, choose the USB to boot from.
After boot system is up, check your available drive,
Delete all partitions on your ssd, and then create 4 partitions, these are partitions from my current installation,
$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 113G 0 disk ├─sda1 │ 8:1 0 1G 0 part /boot ├─sda2 │ 8:2 0 512M 0 part [SWAP] ├─sda3 │ 8:3 0 32G 0 part / └─sda4 8:4 0 79.5G 0 part /home
As you can see my boot partition is 1G, this was actually unintended, everything could go wrong if you did this in the middle of the night. 256Mb should be enough for /boot partition.
Disk: /dev/sda Size: 113 GiB, 121332826112 bytes, 236978176 sectors Label: gpt, identifier: F17EF130-xxxx-xxxx-xxxx-xxxxxxxxxxxx Device Start End Sectors Size Type /dev/sda1 2048 2099199 2097152 1G EFI System /dev/sda2 2099200 3147775 1048576 512M Linux swap /dev/sda3 3147776 70256639 67108864 32G Linux root (x86-64) /dev/sda4 70256640 236978142 166721503 79.5G Linux home
I’m always keep this url open while partitioning cgdisk-walkthrough
# cgdisk /dev/sda
After you’re done, format and mount your newly created partition, File system root / inside the terminal belongs to USB stick, while everything mounted inside /mnt is the target media AKA your SSD.
# mkfs.vfat -F32 /dev/sda1 # mkswap /dev/sda2 # mkfs.ext4 /dev/sda3 # mkfs.ext4 /dev/sda4 # mkdir /mnt/boot && mount /dev/sda1 /mnt/boot # mkdir /mnt/home && mount /dev/sda4 /mnt/home # mount /dev/sda3 /mnt # swapon /dev/sda2
# pacstrap /mnt base base-devel # genfstab -U -p /mnt >> /mnt/etc/fstab
Modify fstab configuration for SSD drive type, this is important, do not skip.
# nano /mnt/etc/fstab
add additional parameters,
Mine will look like this,
# /dev/sda3 UUID=b532cc5e-70c4-431c-80e5-bd9d40440606 / ext4 rw,relatime,data=ordered,discard 0 1 # /dev/sda4 UUID=d5a039d9-c08e-4b26-8e12-9e38bec1fd46 /home ext4 rw,relatime,data=ordered,discard 0 2
Connect the internet
If you’re using ethernet cable or usb cable, you may check your network interface with this,
# ip link 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: wlp2s0b1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000 link/ether 10:40:f3:8c:30:f4 brd ff:ff:ff:ff:ff:ff
My interface is wlp2s0b1
# dhcpcd wlp2s0b1 # ping google.com
If you can use WiFi, connect it with this command,
# arch-chroot /mnt /bin/bash # echo archer > /etc/hostname #Your hostname # ln -s /usr/share/zoneinfo/Asia/Jakarta /etc/localtime # hwclock --systohc --utc
# nano /etc/local.gen
Uncomment UTF8 locale,
#en_SG ISO-8859-1 en_US.UTF-8 UTF-8 #en_US ISO-8859-1
# locale-gen # echo LANG=en_US.UTF-8 > /etc/locale.conf
Add user account,
# useradd -m -g users -G wheel -s /bin/bash yourself && passwd yourself
Change yourself to your liking.
Give yourself sudo rights,
# nano /etc/sudoers # uncomment wheel line
%wheel ALL=(ALL) NOPASSWD: ALL
I’m not goin to dualboot this macbook so then I’m not gonna use GRUB nor REFIND for booting into the system, I’m gonna use systemd-boot to boot into archlinux,
# pacman -S dosfstools intel-ucode # bootctl --path=/boot install
After the systemd-boot (gummiboot) installed, we need to add a boot entries for archlinux.
Create a file for boot entry within this directory path,
First you need to get your root “/” (/dev/sda3) PARTUUID,
# blkid -s PARTUUID -o value /dev/sda3 ed724519-29ca-4e08-b27a-b4852d310dee
Edit the arch.conf file add this entry, replace root PARTUUID with this one ed724519-29ca-4e08-b27a-b4852d310dee
title Arch Linux linux /vmlinuz-linux initrd /intel-ucode.img initrd /initramfs-linux.img options root=PARTUUID=ed724519-29ca-4e08-b27a-b4852d310dee rw quiet
And now lets tell the boot manager to use this arch.conf configuration,
# echo "default arch" > /boot/loader/loader.conf
Before rebooting, you may want to install some network tools,
# pacman install iw wireless_tools wpa_supplicant dialog
also install networkmanager and enable it using NetworkManager.service. Read Arch wiki for more info.
You’re done now for installation, lets reboot,
# exit # umount -R /mnt # sudo reboot // or systemctl reboot
Configure your wifi
You can use wifi-menu, netctl, dhcpd or anything to connect, here we try to use network manager,
$ sudo systemctl disable dhcpcd $ sudo pacman -S networkmanager network-manager-applet $ sudo systemctl enable NetworkManager $ nmcli dev wifi connect <wifi-name> password <password>
Install CPU tools
$ sudo pacman -S cpupower $ sudo systemctl enable cpupower
# Define CPUs governor governor='powersave'
$ sudo pacman -S alsa-utils alsa-plugins
$ sudo pacman -S xorg acpid $ systemctl enable acpid
Install Desktop GUI
$ sudo pacman -S xfce4 xfce4-goodies
Install Display Manager (User Login)
$ sudo pacman -S lightdm lightdm-gtk-greeter-setting $ systemctl enable lightdm.service
Now you’re all set, reboot and enjoy your new Macbook Arch. Things you may need to know, ArchLinux has a community driven repository that you can download and build yourself or using some package manager such as yaourt, pacaur, or trizen for easy install. I’m not goin to explain all of these things it depends to your liking. I’ll leave this to you to explore and have fun with it.
