  • install f3write and f3read tool by type: sudo apt-install f3
  • test write and read on flash mount directory

  1. check sum for verify file corrupt
    sha256sum linux_os_disk.iso
  2. then search online for verify the sum code is same as online provided one
  3. umount usb
    umount /dev/sdb1_like_part_name_for_usb
  4. write
    dd if=linux_os_disk.iso of=/dev/sdb_like_device_Disk_name_check_above
    • if you got error when boot that finished usb like “isolinux.bin missing or corrupt”, means you had dd into its partition with a number instead of sdb_name_like device. use lsblk again to see the name for the DISK or PART
