How to Create a Bootable USB Flash Drive

Using A GNU/Linux System

  1. Download the latest Arch Linux.

    cURL download example, ISO and hashsum files.

    $ curl -JLO https://mirror.csclub.uwaterloo.ca/archlinux/iso/latest/archlinux-2020.08.01-x86_64.iso
    
    $ curl -JLO http://mirror.csclub.uwaterloo.ca/archlinux/iso/latest/sha1sums.txt
    

  2. Verify the download was successful.

    $ sha1sum -c sha1sums.txt
    
    archlinux-2020.08.01-x86_64.iso: OK
    sha1sum: archlinux-bootstrap-2020.08.01-x86_64.tar.gz: No such file or directory
    archlinux-bootstrap-2020.08.01-x86_64.tar.gz: FAILED open or read
    sha1sum: WARNING: 1 listed file could not be read
    

    Note

    The warning message can be ignore since it refers to a file that was not downloaded.

  3. Plug-in the USB flash drive.

  4. Verify the USB device is not mounted and find the device name using one of the following commands.

    $ mount
    
    $ lsblk
    

  5. Write the image to the USB drive. Replace image name (archlinux-2020.08.01-x86_64.iso) and device name (/dev/sdg) with applicable values.

    $ sudo dd bs=4M if=archlinux-2020.08.01-x86_64.iso of=/dev/sdg
    
  6. Run the following command to ensure everything has been completed.

    Note

    Add the package "efibootmgr" if you are using an EFISTUB.

    Note

    Add the package "btrfs-progs" if you are using BTRFS.

  7. Generate and config fstab.

    1. Generate fstab.
      # genfstab -U /mnt/root >> /mnt/root/etc/fstab
      
    2. Edit "/mnt/root/etc/fstab" and change the "2" at the end of entry for "/dev/sda1" to "0".
      # nano /mnt/root/etc/fstab
      
      /dev/sda1    /boot    vfat    rw  0 2

Post-Install Configuration

Required

  1. Enable periodic TRIM.

    Solid State Drive

  2. Enable automatic cleaning of package cache.

    Arch Linux Pacman - Clearing Package Cache

  3. Enable automatic BTRFS scrub. BTRFS scrub is an online file system checking tool. Scrub will determine if data is corrupted and repair corrupted data using duplicate data in RAID storage and checksums.

    Note

    This step is only applicable if using the file system BTRFS.

  4. Install required package.

    # pacman -Sy btrfs-progs
    

  5. Enable Systemd unit timer per BTRFS subvolume (defaults to run monthly).
    # systemctl enable btrfs-scrub@HOME.timer
    
    # systemctl enable btrfs-scrub@SRV.timer
