Previous: Verify the ISO file
References:
Find out the name of your USB drive with lsblk. Edit the variable USBDRIVE accordingly. Make sure that the drive is not mounted. Copy the ISO file to the USB drive using dd:
USBDRIVE="/dev/sdb"
sudo dd bs=4M if=archlinux-x86_64.iso of=$USBDRIVE conv=fsync oflag=direct status=progress
Note: Execute the above command in the same directory where you saved the file archlinux-x86_64.iso (or edit the path in the above command).
