Partition 2 - encrypted partition (LUKS) - remaining storage, code 8309.Partition 1 - EFI partition (ESP) - size 512MiB, code ef00.I use a layout for a single SSD with a GPT partition table that contains two partitions: Links: ArchWiki: Dm-crypt drive preparation and Cryptsetup FAQ 1.9 Partition disk Using if=/dev/urandom is not required as the dm-crypt cipher is used for randomness. dd if=/dev/zero of=/dev/mapper/target bs=1M status=progress oflag=direct This maps the container under /dev/mapper/target with a random password.įill the container with a stream of zeros using dd. cryptsetup open -type plain -d /dev/urandom $ disk target Plain dm-crypt is used for a very fast wipe with randomness.Ĭreate a temporary crypt device (example: target). export disk = "/dev/nvme0n1"ġ.8 Delete old partition layout wipefs -af $ diskġ.8.1 Optional: Fill disk with random data Set a disk variable for use in installation commands.Įxample: In this HOWTO I'm installing to my internal storage device identified as nvme0n1. Identify the internal storage device where Arch Linux will be installed by running lsblk -f. Wireless: Wireless network configuration 1.6 Update system clock timedatectl set-ntp true Some of the instructions below - drive partitioning and GRUB setup in particular - will need to be modified if using BIOS mode. All my current devices use UEFI boot mode and this HOWTO is based on UEFI. Note: If the target device has been manufactured within the last decade, chances are its a UEFI-capable device. If the directory does not exist, the system is booted in BIOS mode. Verify system is booted via UEFI by listing contents of efivars. If UEFI mode is enabled on a UEFI motherboard, the installer will boot Arch accordingly. Switch to a larger font size (example: terminus ter-v24n). Alternative fonts are available in /usr/share/kbd/consolefonts. loadkeys colemakĭefault font in the installer is very small on high resolution displays. Load a different keymap (example: colemak). Now, from the other system, ssh into the Arch installer. 1.2.1 Optional: Continue install from another Linux system via SSHĮnable SSH on the target device. Insert USB installer into target device and boot. sudo dd if=archlinux-RELEASE_VERSION-x86_64.iso of=/dev/sdx bs=4M status=progress oflag=sync ALL DATA ON THE DEVICE WILL BE OVERWRITTEN.Įxample: Under Linux, if a USB drive appears as sdx1, then write the installer to sdx (remove partition number). Write the installer to an unmounted USB drive using the dd command as root.īE VERY CAREFUL TO NOTE THE PROPER DEVICE. Simply copy archlinux-RELEASE_VERSION-x86_64.iso to the USB drive, reboot, and the auto-generated menu lists all the disk images available to boot. I now use Ventoy to create a multiboot installer. Prepare a USB flash drive as an installer using one of these two methods: Unlock system at boot with single passphraseĭownload and verify checksums for archlinux-RELEASE_VERSION-x86_64.iso.BTRFS as root filesystem with multiple subvolumes.unencryted (required) EFI system partition (ESP).GPT partition table with two partitions:.Then arrives the moment of truth, its time to reboot! Once you are up-and-running you will have a system that rolls forward with a continuous, incremental stream of updates to the latest stable versions of software. Boot from the installer to a command-line prompt, and begin crafting your own personal Arch just the way you like it. I've only been using Arch for a few months, but so far its proven stable and a joy to use.
