Minimum system requirements
Arch Linux should run on any i686 compatible machine with a minimum of 256 MB RAM. A basic installation with all packages from the group should take less than 800 MB of disk space. If you are working with limited space, this can be trimmed down considerably, but you will have to know what you are doing.
Prepare the latest installation medium
The installation media and their GnuPG signatures can be acquired from the Download page. The single ISO image supports both 32bit and 64bit systems; this guide assumes you use the latest available version.
It is highly recommended to verify the image signature before use, especially when downloading from an HTTP mirror, as these are run by volunteers who could theoretically serve malicious images. On a system with GnuPG installed, do this by downloading the PGP signature (under Checksums) to the ISO directory, and run:
$ gpg --verify archlinux-version-dual.iso.sig
If the public key is not found, import it with
gpg --recv-keys key-id.
Alternatively, run from an existing Arch Linux installation:
$ pacman-key -v archlinux-version-dual.iso.sig
Now choose one of the methods from the table below to #Boot the installation medium on the target machine(s). As the installation process retrieves packages from a remote repository, these methods require an internet connection; see Offline installation of packages when none is available.
|Write the image on flash media or optical disc, then boot from it.||
|Mount the image on a server machine and have clients boot it over the network.||
|Mount the image in a running Linux system and install Arch from a chroot environment.|
|Set up a virtual machine and install Arch as a guest system.||
Boot the installation medium
Point the current boot device to the media containing the Arch installation media. This is typically achieved by pressing a key during the POST phase, as indicated on the splash screen. Refer to your motherboard's manual for details.
When the Arch menu appears, select "Boot Arch Linux" and press
Enter to enter the live environment where you will perform the actual installation. Various boot parameters (for example,
copytoram) can be used by editing the boot entry (
tab for syslinux and
e for gummiboot), see README.bootparams for reference.
You will be presented with a Zsh shell prompt, logged in as the root user. Zsh provides advanced tab completion and other features as part of the grml config. For editing text files, the console editor nano is suggested.
Booting into UEFI mode
Arch Linux archiso x86_64 UEFI USB UEFI Shell x86_64 v1 UEFI Shell x86_64 v2 EFI Default Loader
To verify you are booted in UEFI mode, run:
# efivar -l
Should efivar not list the UEFI variables properly, check if all requirements are met.
Troubleshooting boot problems
- If you are using an Intel video chipset and the screen goes blank during the boot process, the problem is likely an issue with Kernel mode setting. A possible workaround may be achieved by rebooting and pressing
Tabover the entry that you are trying to boot (i686 or x86_64). At the end of the string type
Enter. Alternatively, try
video=SVIDEO-1:dwhich, if it works, will not disable kernel mode setting. You can also try
i915.modeset=0. See the Intel article for more information.
- If the screen does not go blank and the boot process gets stuck while trying to load the kernel, press
Tabwhile hovering over the menu entry, type
acpi=offat the end of the string and press
# loadkeys layout
where layout is a two-letter country code. Use
localectl list-keymaps to list all available keymaps.
If certain special characters appear as white squares or other symbols, you may wish to change the console font. See Fonts#Previewing_and_testing for details.
Establish an internet connection
ip linkto discover the names of your interfaces.
The dhcpcd network daemon starts automatically during boot of the live system and will attempt to start a wired connection. Try to ping a server to see if a connection was established. For example, Google's webservers:
# ping -c 3 www.google.com
PING www.l.google.com (18.104.22.168) 56(84) bytes of data. 64 bytes from wb-in-f105.1e100.net (22.214.171.124): icmp_req=1 ttl=50 time=17.0 ms 64 bytes from wb-in-f105.1e100.net (126.96.36.199): icmp_req=2 ttl=50 time=18.2 ms 64 bytes from wb-in-f105.1e100.net (188.8.131.52): icmp_req=3 ttl=50 time=16.6 ms --- www.l.google.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 16.660/17.320/18.254/0.678 ms
If you get a
ping: unknown host error, first check if there is an issue with your cable. If not, you will need to set up the network manually, as explained below. Once a connection is established move on to #Prepare the storage devices.
- The elinks browser is available in the live system: it can be useful for example to authenticate in RADIUS-protected networks.
- The system you are going to install in this guide makes no pre-assumptions regarding network access. For an easy start after the first boot, it may be helpful to stick to the method that got you connected with the live medium and copy relevant configuration to the new system before you #Chroot and configure the base system later.
Follow this procedure if you need to set up a wired connection via a static IP address.
Identify the name of your ethernet interface:
# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp2s0f0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:11:25:31:69:20 brd ff:ff:ff:ff:ff:ff 3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT qlen 1000 link/ether 01:02:03:04:05:06 brd ff:ff:ff:ff:ff:ff
In this example, the ethernet interface is
enp2s0f0. If you are unsure, your ethernet interface is likely to start with the letter "e", and unlikely to be "lo" or start with the letter "w".
See Network_configuration#Static_IP_address for required settings. Configure a static profile for dhcpcd in
/etc/dhcpcd.conf with your settings, for example:
interface enp2s0f0 static ip_address=192.168.0.10/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.1 184.108.40.206
# systemctl restart dhcpcd.service
You should now have a working network connection. If you do not, see Network configuration page.
/usr/lib/firmwarein the live environment (on CD/USB stick) but must be explicitly installed to your actual system to provide wireless functionality after you reboot into it! Package installation is covered later in this guide. Ensure installation of both your wireless module and firmware before rebooting! See Wireless network configuration if you are unsure about the requirement of corresponding firmware installation for your particular chipset.
Use netctl's wifi-menu to connect to a wireless network:
This should bring you a menu of wifi networks if your computer has only one Wi-Fi device (mostly the case in laptops).
If your computer has more than one Wi-Fi device, you need to choose one and pass its interface name to wifi-menu. First, identify the name of the needed interface:
# iw dev
phy#0 Interface wlp3s0 ifindex 3 wdev 0x1 addr 00:11:22:33:44:55 type managed
This example shows
wlp3s0 as the only available wireless interface, for simplicity. If you are unsure, wireless interfaces are likely to start with the letter "w", and unlikely to be "lo" or start with the letter "e".
Now try wifi-menu again by passing it the interface name:
# wifi-menu wlp3s0
See the sample configuration in WPA2 Enterprise#netctl for networks that require both a username and password.
You should now have a working wireless network connection. If you do not or even failed to identify the wireless interface, see #Without wifi-menu below or the detailed Wireless network configuration page.
Bring the interface up with:
# ip link set wlp3s0 up
To verify that the interface is up, inspect the output of the following command:
# ip link show wlp3s0
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000 link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
<BROADCAST,MULTICAST,UP,LOWER_UP> is what indicates the interface is up, not the later
Most wireless chipsets require firmware in addition to a corresponding driver. The kernel tries to identify and load both automatically. If you get output like
SIOCSIFFLAGS: No such file or directory, this means you will need to manually load the firmware. If unsure, invoke dmesg to query the kernel log for a firmware request from the wireless chipset. For example, if you have an Intel chipset which requires and has requested firmware from the kernel at boot:
# dmesg | grep firmware
firmware: requesting iwlwifi-5000-1.ucode
If there is no output, it may be concluded that the system's wireless chipset does not require firmware.
Next, scan for available networks using
iw dev wlp3s0 scan | grep SSID, then connect to a network with:
# wpa_supplicant -B -i wlp3s0 -c <(wpa_passphrase "ssid" "psk")
You need to replace
ssid with the name of your network and
psk with your wireless password, leaving the quotes around the network name and password.
Finally, you have to give your interface an IP address. This can be set manually or using dhcp:
# dhcpcd wlp3s0
If that does not work, issue the following commands:
# echo 'ctrl_interface=DIR=/run/wpa_supplicant' > /etc/wpa_supplicant.conf # wpa_passphrase "ssid" "psk" >> /etc/wpa_supplicant.conf # ip link set interface up # wpa_supplicant -B -D nl80211,wext -c /etc/wpa_supplicant.conf -i interface # dhcpcd -A interface
Setting the interface up at step 3 may not be needed, but does no harm in any case.

For xDSL, dial-up, and ISDN connections, see Direct Modem Connection.
Behind a proxy server
If you are behind a proxy server, you will need to export the
ftp_proxy environment variables. See Proxy settings for more information.
Prepare the storage devices
In this step, the storage devices that will be used by the new system will be prepared. Read Partitioning for a more general overview.
Identify the devices
The first step is to identify the devices where the new system will be installed. The following command will show all the available devices:
This will list all devices connected to your system along with their partition schemes, including that used to host and boot live Arch installation media (e.g. a USB drive). Not all devices listed will therefore be viable or appropriate mediums for installation. To filter out inappropriate results, the command can optionally be amended as follows:
# lsblk | grep -v "rom\|loop\|airoot"
Devices (e.g. hard disks) will be listed as
x is a lower-case letter starting from
a for the first device (
b for the second device (
sdb), and so on. Existing partitions on those devices will be listed as
Y is a number starting from
1 for the first partition,
2 for the second, and so on. In the example below, only one device is available (
sda), and that device uses only one partition (
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 80G 0 disk └─sda1 8:1 0 80G 0 part
sdxY convention will be used in the examples provided below for partition tables, partitions, and file systems. As they are just examples, it is important to ensure that any necessary changes to device names, partition numbers, and/or partition sizes (etc.) are made. Do not just blindly copy and paste the commands.
If the existing partition scheme needs not be changed, skip to #Create filesystems, otherwise continue reading the following section.
Partition table types
If you are installing alongside an existing installation (i.e. dual-booting), a partition table will already be in use. If the devices are not partitioned, or the current partitions table or scheme needs to be changed, you will first have to determine the partition tables (one for each device) in use or to be used.
There are two types of partition table:
Any existing partition table can be identified with the following command for each device:
# parted /dev/sdx print
For each device to be partitioned, a proper tool must be chosen according to the partition table to be used. Several partitioning tools are provided by the Arch installation medium, including:
Using parted in interactive mode
All the examples provided below make use of parted, as it can be used for both BIOS/MBR and UEFI/GPT. It will be launched in interactive mode, which simplifies the partitioning process and reduces unnecessary repetition by automatically applying all partitioning commands to the specified device.
In order to start operating on a device, execute:
# parted /dev/sdx
You will notice that the command-line prompt changes from a hash (
(parted): this also means that the new prompt is not a command to be manually entered when running the commands in the examples.
To see a list of the available commands, enter:
When finished, or if wishing to implement a partition table or scheme for another device, exit from parted with:
After exiting, the command-line prompt will change back to
Create new partition table
You need to (re)create the partition table of a device when it has never been partitioned before, or when you want to change the type of its partition table. Recreating the partition table of a device is also useful when the partition scheme needs to be restructured from scratch.
- If dual-booting with an existing installation of Windows on a UEFI/GPT system, do not erase the partition table. Doing so will destroy all existing data on the device, including the UEFI partition with the Windows .efi file required to boot it.
- MBR is designed specifically for use with BIOS systems, and GPT is designed for UEFI. It is not recommended for less experienced users to break this convention as both have features and/or limitations that may be incompatible with your hardware (e.g. MBR cannot cope with devices larger than 2 TiB).  If for any reason you do not wish to follow this convention, see  and  for more information and possible workarounds.
Open each device whose partition table must be (re)created with:
# parted /dev/sdx
To then create a new MBR/msdos partition table for BIOS systems, use the following command:
(parted) mklabel msdos
To create a new GPT partition table for UEFI systems instead, use:
(parted) mklabel gpt
You can decide the number and size of the partitions the devices should be split into, and which directories will be used to mount the partitions in the installed system (also known as mount points). The mapping from partitions to directories is the partition scheme, which must comply with the following requirements:
- At least a partition for the
/(root) directory must be created.
- Depending on the motherboard's firmware interface, the chosen #Partition table types, and in some cases also the chosen boot loader, the following additional partitions must be created:
- BIOS/MBR: no additional partition required.
- UEFI/GPT: one EFI System Partition.
In the examples below it is assumed that a new and contiguous partitioning scheme is applied to a single device. Some optional partitions will also be created for the
/home directories: see also Arch filesystem hierarchy for an explanation of the purpose of the various directories; if separate partitions for directories like
/home are not created, these will simply be contained in the
/ partition. Also the creation of an optional partiton for swap space will be illustrated.
If not already open in a parted interactive session, open each device to be partitioned with:
# parted /dev/sdx
The following command will be used to create partitions:
(parted) mkpart part-type fs-type start end
part-typeis one of
logical, and is meaningful only for MBR partition tables.
fs-typeis an identifier chosen among those listed by entering
help mkpartas the closest match to the file system that you will use in #Create filesystems. The mkpart command does not actually create the file system: the
fs-typeparameter will simply be used by parted to set a 1-byte code that is used by boot loaders to "preview" what kind of data is found in the partition, and act accordingly if necessary. See also Wikipedia:Disk partitioning#PC partition types.
startis the beginning of the partition from the start of the device. It consists of a number followed by a unit, for example
1Mmeans start at 1MiB.
endis the end of the partition from the start of the device (not from the
startvalue). It has the same syntax as
start, for example
100%means end at the end of the device (use all the remaining space).
Warning: The resulting partition is not properly aligned for best performance. Ignore/Cancel?In this case, read Partitioning#Partition alignment and follow GNU Parted#Alignment to fix it.
The following command will be used to flag the partition that contains the
/boot directory as bootable:
(parted) set partition boot on
partitionis the number of the partition to be flagged (see the output of the
In every instance, a special bootable EFI System Partition is required.
If creating a new EFI System Partition, use the following commands (the recommended size is 512MiB):
(parted) mkpart ESP fat32 1MiB 513MiB (parted) set 1 boot on
The remaining partition scheme is entirely up to you. For one other partition using 100% of remaining space:
(parted) mkpart primary ext3 513MiB 100%
/ (20GiB) and
/home (all remaining space) partitions:
(parted) mkpart primary ext3 513MiB 20.5GiB (parted) mkpart primary ext3 20.5GiB 100%
And for separate
/ (20GiB), swap (4GiB), and
/home (all remaining space) partitions:
(parted) mkpart primary ext3 513MiB 20.5GiB (parted) mkpart primary linux-swap 20.5GiB 24.5GiB (parted) mkpart primary ext3 24.5GiB 100%
For a minimum single primary partition using all available disk space, the following command would be used:
(parted) mkpart primary ext3 1MiB 100% (parted) set 1 boot on
In the following instance, a 20GiB
/ partition will be created, followed by a
/home partition using all the remaining space:
(parted) mkpart primary ext3 1MiB 20GiB (parted) set 1 boot on (parted) mkpart primary ext3 20GiB 100%
In the final example below, separate
/ (20GiB), swap (4GiB), and
/home (all remaining space) partitions will be created:
(parted) mkpart primary ext3 1MiB 100MiB (parted) set 1 boot on (parted) mkpart primary ext3 100MiB 20GiB (parted) mkpart primary linux-swap 20GiB 24GiB (parted) mkpart primary ext3 24GiB 100%
Once the partitions have been created, each must be formatted with an appropriate file system, except for swap partitions. All available partitions on the intended installation device can be listed with the following command:
# lsblk /dev/sdx
With the exceptions noted below, it is recommended to use the
ext4 file system:
# mkfs.ext4 /dev/sdxY
- If dual-booting with an existing installation of Windows on a UEFI/GPT system, do not re-format the UEFI partition. Doing so will destroy all existing data on that partition, including the Windows .efi file required to boot it.
- If a new UEFI system partition has been created on a UEFI/GPT system, it must be formatted with a
vfat32file system. Failure to do so will result in an unbootable installation:
# mkfs.vfat -F32 /dev/sdxY
If a swap partition has been created, it must be set up and activated with:
# mkswap /dev/sdxY # swapon /dev/sdxY
Mount the partitions
/ (root) partition must be mounted first: this is because any directories such as
/home that have separate partitions will have to be created in the root file system. The
/mnt directory of the live system will be used to mount the root partition, and consequently all the other partitions will stem from there. If the root partition's name is
# mount /dev/sdxR /mnt
/ partition has been mounted, any remaining partitions may be mounted in any order. The general procedure is to first create the mount point, and then mount the partition to it. If using a separate
# mkdir -p /mnt/boot # mount /dev/sdxB /mnt/boot
/bootis recommended also for mounting the EFI System Partition on UEFI/GPT system. See EFISTUB and related articles for alternatives.
If using a separate
# mkdir -p /mnt/home # mount /dev/sdxH /mnt/home
Once all the remaining partitions, if any, have been mounted, the devices are ready to install Arch.
Select a mirror
You may want to edit the
mirrorlist file and place your preferred mirror first. A copy of this file will be installed on your new system by pacstrap as well, so it is worth getting it right.
# nano /etc/pacman.d/mirrorlist
## ## Arch Linux repository mirrorlist ## Sorted by mirror score from mirror status page ## Generated on YYYY-MM-DD ## Server = http://mirror.example.xyz/archlinux/$repo/os/$arch ...
If you want, you can make it the only mirror available by deleting all other lines, but it is usually a good idea to have a few more, in case the first one goes offline. Should you change your mirror list at a later stage, refresh all package lists with
pacman -Syyu. See Mirrors for more information.
Install the base system
The base system is installed using the pacstrap script. Without the
-i switch, every package from the group is installed without prompting. To build packages from the AUR or with ABS, you will also need the group.
# pacstrap -i /mnt base base-devel
Other packages can be installed later using pacman.
Generate an fstab
# genfstab -U -p /mnt >> /mnt/etc/fstab # cat /mnt/etc/fstab
fstabfile should always be checked after generating it. If you encounter errors running genfstab or later in the install process, do not run genfstab again; just edit the
fstabfile. See fstab#Field definitions for syntax information.
Chroot and configure the base system
Next, chroot into your newly installed system:
# arch-chroot /mnt /bin/bash
At this stage of the installation, you will configure the primary configuration files of your Arch Linux base system. These can either be created if they do not exist, or edited if you wish to change the defaults.
Closely following and understanding these steps is of key importance to ensure a properly configured system.
Locales define which language the system uses and other regional considerations, such as currency denomination, numerology and character sets. Possible values are listed in
/etc/locale.gen, with the active locale defined in
All entries in
locale.gen are commented out (preceded by
#) by default. Uncomment
en_US.UTF-8 UTF-8, as well as other needed localisations.
UTF-8 is highly recommended over other options.
# nano /etc/locale.gen
... #en_SG ISO-8859-1 en_US.UTF-8 UTF-8 #en_US ISO-8859-1 ...
Before locales can be enabled, they must be generated:
LANG refers to the first column of an uncommented entry in
# echo LANG=en_US.UTF-8 > /etc/locale.conf
Export the chosen locale:
# export LANG=en_US.UTF-8
en_US.UTF-8as the system locale allows to keep system logs in English for easier troubleshooting. Users may override this setting for their session as described in Locale#Setting the locale.
LANGacts as the default value for the locale-related
LC_*variables. To use other locales for these variables, run locale to see the available options and add them to
locale.conf. It is not recommended to set the
LC_ALLvariable. See Locale for details.
Console font and keymap
If you changed the default console keymap and font in #Keyboard layout, create
/etc/vconsole.conf to make those changes persist in the installed system. It is important
KEYMAP matches the value initially set with
loadkeys, to ensure correct entry of the root password on reboot.
# nano /etc/vconsole.conf
Available time zones and subzones can be found in the
/usr/share/zoneinfo/Zone/SubZone directories, and listed with the ls command. Create a symbolic link
/etc/localtime to your subzone file
# ln -s /usr/share/zoneinfo/Zone/SubZone /etc/localtime
You may use tab completion to show available zones and subzones. Example:
# ln -s /usr/share/zoneinfo/Europe/Minsk /etc/localtime
If you get
ln: failed to create symbolic link '/etc/localtime': File exists, check the existing file with
ls -l /etc/localtime and add the
-f option to the ln command to overwrite it.
If you have multiple operating systems installed in the same machine, they will all derive the current time from the same hardware clock, which must be set to either UTC or localtime. For this reason you must make sure that all the operating systems see the hardware clock as providing time in the same chosen standard, otherwise some of them will perform the time zone adjustement for the system clock, while others will not.
In particular, it is strongly recommended to set the hardware clock to UTC, in order to avoid conflicts between the installed operating systems. For example, if the hardware clock was set to localtime, more than one operating system may adjust it after a DST change, thus resulting in an overcorrection; more problems may arise when travelling between different time zones and using one of the operating systems to reset the system/hardware clock.
To set the hardware clock to UTC in Linux, run:
# hwclock --systohc --utc
The hwclock command also generates the
Set the hostname to your liking:
# echo myhostname > /etc/hostname
Configure the network
You need to configure the network again, but this time for your newly installed environment. The procedure and prerequisites are similar to the one described above, except we are going to make it persistent and automatically run at boot.
As a first step, identify the network interface name you want to configure the connection for with
- For more in-depth information on network configuration, visit Network configuration and Wireless network configuration.
- If you would like to use the old interface naming scheme (i.e.
wlanX) you can accomplish this by creating an empty file at
/etc/udev/rules.d/80-net-setup-link.ruleswhich will mask the file of the same name located under
Now select a daemon to handle the configuration and operation. Several are listed below; only select one of them for the new system.
- Using dhcpcd
A simple option for adapter configuration is to use the DHCP Client Daemon, the method used by default with the install medium. See Dhcpcd#Running.
Users requiring only single wired network connection can simply enable the dhcpcd service for the interface:
# systemctl enable dhcpcd@interface_name.service
If static IP settings are required, adjust the profile configuration as described in #Static IP.
- Using systemd-networkd
- Using netctl
Another option is netctl which is a CLI-based tool used to configure and manage network connections via user-created profiles. Create a profile as shown in netctl#Example profiles, then enable it as described in netctl#Basic method.
All of the tools listed in #Wired above can activate wireless connections. For wireless, however, dhcpcd and systemd-networkd require a separate configuration of the connection in the wireless backend, wpa_supplicant, first. If you anticipate to connect the machine to different wireless networks over time, a tool which provides its own connection management may be easier to handle. Aside from netctl introduced below, Wireless network configuration#Automatic setup lists other choices.
# pacman -S zd1211-firmwareSee Wireless network configuration#Installing driver/firmware for more info.
Installand which you will need to connect to a network:
# pacman -S iw wpa_supplicant
Adding wireless networks
- Using wifi-menu
Install, which is required for wifi-menu:
# pacman -S dialog
After finishing the rest of this installation and rebooting, you can connect to the network with:
# wifi-menu interface_name
interface_name is the interface of your wireless chipset.
- Using manual netctl profiles
Copy a network profile from
# cd /etc/netctl # cp examples/wireless-wpa my-network
Edit the profile as needed (modify
# nano my-network
Enable above created profile to start it at every boot:
# netctl enable my-network
Connect automatically to known networks
netctl enable profile.
# pacman -S wpa_actiond
netctl-auto service, which will connect to known networks and gracefully handle roaming and disconnects:
# systemctl enable netctl-auto@interface_name.service
netctl-ifplugd, which can be used to handle wired profiles in conjunction with
Analog modem, ISDN or PPPoE DSL
For xDSL, dial-up and ISDN connections, see Direct Modem Connection.
Create an initial ramdisk environment
As mkinitcpio was run on installation of with pacstrap, most users can use the defaults provided in
mkinitcpio.conf. For special configurations, set the correct hooks in
/etc/mkinitcpio.conf and re-generate the initramfs image.
Set the root password
Set the root password with:
Install and configure a bootloader
For BIOS motherboards
Here, installation with GRUB and MBR is demonstrated.
Install thepackage; to have GRUB search for other installed operating systems, install in addition:
# pacman -S grub os-prober
Install the bootloader to the drive Arch was installed to (do not append a partition number, or
# grub-install --target=i386-pc --recheck /dev/sda
# grub-mkconfig -o /boot/grub/grub.cfg
/boot/grub/grub.cfgis included with the package, and subsequent
grub-*commands may not over-write it. Ensure your intended changes are in
grub.cfg, rather than in
grub.cfg.newor similar file.
For more information on configuring and using GRUB, see GRUB.
For UEFI motherboards
Here, installation with gummiboot is demonstrated. First installto manipulate the EFI System Partition post-installation, and to create a UEFI boot entry (used by bootmanager installation scripts):
# pacman -S dosfstools efibootmgr
- For UEFI boot, the drive needs to be GPT-partitioned and an EFI System Partition (512 MiB or larger, gdisk type
EF00, formatted with FAT32) must be present. In the following examples, this partition is assumed to be mounted at
/boot. If you have followed this guide from the beginning, you have already done all of these.
- It is strongly recommended to have the EFI System Partition mounted at
/bootas this is required to automatically update Gummiboot.
$esp with the location of your EFI System Partiton, usually
# pacman -S gummiboot # gummiboot --path=$esp install
Gummiboot will automatically be detected by firmware that requires that the bootable
bootx64.efi stub be placed in
$esp/EFI/boot, and will in turn automatically detect the presence of any other installed operating systems using .efi stubs. However, it will still be necessary to manually create a configuration file for Gummiboot.
$esp/loader/entries/arch.conf and add the following, replacing
/dev/sdaX with your root partition (most likely
/dev/sda1 is the ESP):
# nano $esp/loader/entries/arch.conf
title Arch Linux linux /vmlinuz-linux initrd /initramfs-linux.img options root=/dev/sdaX rw
$esp/loader/loader.conf and add the following, replacing the timeout value (in seconds) with your own choice:
# nano $esp/loader/loader.conf
default arch timeout 5
See gummiboot for more information.
Unmount the partitions and reboot
Exit from the chroot environment:
Reboot the computer. Partitions will be unmounted automatically by systemd on shutdown. You may however unmount with
umount -R /mnt as a safety measure (if the partition is "busy", you can find the cause with fuser).
Remove the installation media, or you may boot back into it. You can log into your new installation as root, using the password you specified with passwd.
Your new Arch Linux base system is now a functional GNU/Linux environment ready to be built into whatever you wish or require for your purposes. You are now strongly advised to read the General recommendations article, especially the first two sections. Its other sections provide links to post-installation tutorials like setting up a graphical user interface, sound or a touchpad.
