How to create a bootable USB key from ISO image on linux command line ?
To create a bootable USB memory on linux you have several solutions. The famous dd is the most powerful solution, but use carefully. Because a very small error may destroy all your data.
1. Fiend the USB device name using lsblk ( or disk utility GUI).
Ex:
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465,8G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 16M 0 part
├─sda3 8:3 0 853M 0 part /boot/efi
├─sda4 8:4 0 19,5G 0 part /
├─sda5 8:7 0 4,1G 0 part [SWAP]
sdb 8:16 1 960M 0 disk
└─sdb1 8:17 1 959M 0 part /media/me/3377-46AF
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465,8G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 16M 0 part
├─sda3 8:3 0 853M 0 part /boot/efi
├─sda4 8:4 0 19,5G 0 part /
├─sda5 8:7 0 4,1G 0 part [SWAP]
sdb 8:16 1 960M 0 disk
└─sdb1 8:17 1 959M 0 part /media/me/3377-46AF
Here, the usb device name is sdb , so the path is /dev/sdb
2. Copy ISO file using dd.
The syntax is : $ dd if=PATH_TO_ISO_FILE of=/dev/sdX
Example : $ dd if=os/linux-mint-18.iso of=/dev/sdb
Note : usually you must do it as root or use sudo
