To create a bootable USB just type:

sudo dd bs=4M if=OS.iso of=/dev/sdb status=progress && sync

Where "if" get iso file address that we want to use in bootable usb and "of" is the device block that we want to be bootable. In my situation /dev/sdb". "status=progress" make process verbose and "bs=4M" tell us about amounts that in every cycle write to USB device.

To restore USB just follow below steps:

sudo wipefs --all /dev/sdb

sudo cfdisk /dev/sdb

* SELECT dos

* ENTER
* SELECT primary
* SELECT write
* TYPE yes

sudo mkfs.vfat -n 'LEBEL' /dev/sdb1
