If you have a new Laptop and you planned to install a Linux any distribution OS on it but the laptop is a new hardware model and doesn't have a CD / DVD drive as most of notebook nowadays you might be wondering how to setup USB Linux bootable image, well you can simply use your favorite distro provided ISO (Debian / Ubuntu / Fedora) whatever burn it to a USB flash drive and boot from USB the Linux installer program. of course assuming ou have it configured in your UEFI BIOS.
For the task you need to Burn the respecive distribution ISO to the USB using simple command line.
To do so simply download your Linux distribution latest ISO file and issue with root in physical terminal / gnome-terminal or konsole.
cat debian-linux-iso-name.iso > /dev/sdb; sync
WARNING DATA DANGEROUS!!!
If you happen to keep any data on the USB flash drive, above command would wipe it out from USB drive so be sure to prepare your existing data a backup somewhere before proceeding.
Also beware to not provide the wrong /dev/sdb device to the command as you might end up wiping out your Hard Drive ( SDD ) drives or other attached external hard drives under /dev/sdb.
Thus in advance be sure to check the exact USB /dev/ name using commands such as:
linux:~# fdisk -l
Disk /dev/sdb: 3.8 GiB, 4007657472 bytes, 7827456 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x04030201
Device Boot Start End Sectors Size Id Type
/dev/sdb1 1080 7827455 7826376 3.7G c W95 FAT32 (LBA)
linux:~# dmesg|grep -i sdb
dmesg – output is pretty verbose so I'm skipping completely its output.

linux:~# lsblk |grep -i /media

An alternative way is to use the good old dd tool.
linux:~# dd if=/your/path/debian-7.5.0-amd64-netinst.iso of=/dev/sdb bs=4M
Its even possible to create the bootable Linux image to USB with a simple cp command instead of catting like:
linux:~# cp Fedora-Workstation-Live-x86_64-28-1.1.iso /dev/sdX
Finally unmount the USB drive (if it was mounted during the command operations):
For Windows users to burn the ISO files you can use anything starting from Nero / CDBurnerXP or if you prefer free software use
Win32DiskImager or use Rufus to create it.
Enjoy booting and installing your Linux via USB 🙂
