Finally, I was able to install pure Arch Linux.. I mean not a distribution of Arch. Just pure Arch Linux. So I thought to share it. Note : I first tried this on a Virtual Machine. But it went well, so I tried it on my PC and now it is running Arch.. 🙂
Download newest Arch Linux ISO file from here. And make a bootable CD/DVD or a USB drive. If you are using a VM, you just need the .iso file. I tried UNetBootin, but it gave me some errors and couldn’t get the USB booted. I’d found out that it is a problem with UNetBootin.So I used
dd command in Linux to copy the ISO file into the USB. Look into this for more info. Then boot the computer (or VM) with the Arch Bootable device. Then you will be prompted to Arch Installation menu. Select the appropriate installation architecture. (In this case, I’ve selected “Boot Arch Linux (x86_64)” since I needed the 64 bit mode.) Now you will be prompted to the Arch installation terminal.
First, you have to partition your hard disk. You may need a separate partition for swap as well. And you even can use separate partitions for root and boot as well. But in here, I only use a single partition + a swap partition (optional). You can use the
cfdisk command to create the partitions. Create a
Linux partition for the installation and a
swap partition for the
If you have many physical disks, you can specify the hard disk as following.
$ cfdisk /dev/sda
Do not forget to make the main Linux partition Bootable. After finalizing the partition table, use
write option to write the partition table into the disk. Then quit. Now you have to format the partitions. You can use
mkfs command for that. (Please note that we use partition names, not disk names.)
$ mkfs.ext4 /dev/sda1
To create the swap partition.
$ mkswap /dev/sda2 Then you have to mount the partitions.
$ mount /dev/sda1 /mnt $ swapon /dev/sda2
Now you are ready to go.
Before installing, you may need to configure your network settings.
$ ip addr add <ip_address>/<sub_net_mask> dev <device_name>
$ ip addr add 10.22.40.201/255.255.255.0 dev enp0s25
Define the default gateway.
$ ip route add default via <gateway>
$ ip route add default via 10.22.40.254
If you need a separate DNS,
/etc/resolv.conf and add,
Install the base system using,
$ pacstrap /mnt base base-devel
Then generate the fstab file by,
$ genfstab -p /mnt >> /mnt/etc/fstab
Now, change the root to the installation.
$ arch-chroot /mnt
Now this is your Arch Linux installation. We have to create the init ram disk file by,
$ mkinitcpio -p linux
Don’t forget to change the root password.
$ passwd root
Type a new password and confirm it. Then add a normal user for the system by,
$ useradd -m -g users -G wheel -s /bin/bash praneeth
Replace praneeth with any name you want. It will be the user name. Then add a password to that user by,
$ passwd praneeth
Type a new password and confirm it. Now you can add this user to the sudoers list.
$ nano /etc/sudoers
Then look for
# user privileges (using
Ctrl + W) and after the root entry, add,
praneeth ALL = (ALL) ALL
Then save and exit. (using
Ctrl + X) Before you proceed, it is better to upgrade the system by,
$ pacman –Syu
It will install many needed packaged including
grub. Now you can configure the grub by,
$ grub-mkconfig -o /boot/grub/grub.cfg
It will generate the grub configuration file. If you get an error (as I did), you have to edit the default configuration file.
$ nano /etc/default/grub
And add the following line to the end of the file.
GRUB_DISABLE_SUBMENU = y
Now create the grub configuration file again with,
$ grub-mkconfig -o /boot/grub/grub.cfg
It should work. Now install the grub on the hard disk. (Not on the partition.)
$ grub-install /dev/sda
It will create a new boot loader and it may replace any other boot loader, such as Windows boot loader. Then you have to install
os-prober in order to detect them and add them to Linux grub. Hence, it is recommended to to do that before generating the grub config. If you already had, just run the above two commands again.
$ pacman -S os-prober
That’s it. Now you are ready. But…. When I installed Arch, I had to face a problem with my wi-fi drivers and my computer did not get booted. So I’ve found a way round for that. You have to install the basic firmware for the wi-fi devices. But it is not in the official repositories. You have to build it from user repositories. For that, you need
packer command. But it is also not in the official repositories. So first you have to download
packer PKGBUILD file and build it. But still you need few packages to build it.
$ pacman -S wget fakeroot jshon expac git binutils
Then download the packer
PKGBUILD file. First cd to your home directory, since you don’t need mess on the root directory.
$ cd /home/praneeth $ wget https://aur/archlinux.org/packages/pa/packer/PKGBUILD $ makepkg
packer package is built as a .tar.xz file. Then use
–U option in
pacman to install it.
$ pacman -U /packer-<something.something..>.tar.xz
Now you can install the wi-fi firmware by,
packer -S b43-firmware
Now you are done…!!! exit the chroot, unmount and reboot. (And remove the bootable device)
$ exit $ umount /dev/sda1 ( $ umount /dev/sda2) $ reboot
If you did everything right, now you will be prompted to the Arch Login. Login using the normal user account. First, we’ll change the
hostname of the computer.
$ sudo nano /etc/hostname
Then type a desired hostname. You normally should be connected to internet after login. If not, simply enable DHCPC service by,
$ sudo pacman -S dhcp $ sudo systemctl enable dhcpcd $ sudo systemctl start dhcpcd
Then enable locales by editing and uncommenting the needed locales.
$ sudo nano /etc/locale.gen
I uncommented en_US.UTF-8 UTF-8, en_US ISO-8859-1 and si_LK UTF-8. Then we can apply these changes by running,
$ sudo locale-gen
Install a desktop environment.
To get on with Arch Linux, it is better to use a desktop environment. I’m going to install LXDE here. (I tried XFCE4, but it was not working properly with new Arch versions.)
$ sudo pacman -S xorg xterm xorg-clock xorg-twm xorg-xinit xorg-server-utils mesa lxde lxdm
After installing, enable LXDM by,
$ sudo systemctl enable lxdm
You can restart or start LXDM straight away by,
$ sudo systemctl start lxdm
Everything should work smoothly now.
Cheers..!! You have successfully installed Arch Linux on your computer..

[…] will generate the grub configuration file. If you get an error (as I did in this post), you have to edit the default configuration […]
Thanks for the guide! I’m wondering if something bigger changed on this latest release (as of 2/2/2015) because no matter if I use fdisk or cfdisk I cannot figure out how to make a partition bootable. cfdisk itself seems to have changed and does not allow you to set a new partition bootable or not.
Am I missing some details? My Google-fu has failed me but maybe I just haven’t been using the best terms. Everything about cfdisk and fdisk I pull up are from years ago and do not reflect this newer version.
Have you tried GUID Partitioning ? That might help.
Please refer these and see if it applies in your case.
