This is for linux beginners, simple how-to create bootable usb from terminal. DD command takes input and duplicate it, and it's exactly what we need.

1. Full Command Explained
$ sudo dd if=Ubuntu.iso of=/dev/sdb bs=8M status=progress && sync
-
sudo- give you root access -
dd- command to duplicate disk -
if- name of file you want to write -
of- name of USB device -
bs- size of bytes to write at a time -
status- show status progress during duplication -
sync- synchronize writes
2. Fill Device With Zero (optional)
If you have some damaged fields on USB, fill it with zero first:
sudo dd if=/dev/zero of=/dev/sdb bs=8M status=progress && sync
-
zero- will delete everything on USB, including partitions - Run
dd zeroBEFORE you write file to USB - If you need to make a new partition, take a look at FDISK tutorial
3. Make Process Automatic (for future use)
- Symlink script in /bin/ folder to make it available within the system
ln -s /path/to/writeusb.sh /bin/writeusb
- Change download folder to any folder you want
#!/bin/bash
# Check Root User
if [ $(id -u) != "0" ]; then
echo -e "$W"" You must have root access to run this script!\n"$RS" "
sleep 1
exit
