Rufus is a portable utility that allows you to create bootable USB drives for Windows and Linux. It also allows you to check the USB device for bad blocks, using up to four passes. Rufus runs in both 32-bit and 64-bit versions of Microsoft Windows. You can create bootable USB drives for the listed versions of Windows, as well as almost all popular Linux distributions.  You can also use Rufus to put utilities on USB drives, such as Parted, Ultimate Boot CD, and BartPE.

Example: To create a bootable Windows 7 installer from Rufu’s settings, Choose NTFS as the file system.  Then check the option for "Quick format" and "Create extended label and icon files."  Now check "Create a bootable disk using" and select your ISO file.

=== WoeUSB ===
* http://www.webupd8.org/2017/06/tool-to-create-bootable-windows-usb.html

Create Bootable Windows USB drive from Linux.  WoeUSB is a fork of the obsolete WinUSB.  You are running linux and you need to take a MS Windows ISO image to create a bootable USB drive (for the purpose of installing Windows) then WoeUSB is a quick and easy solution.  WoeUSB can create bootable USB media for Windows from Windows ISO images or DVDs.

Ubuntu 14.04 and Ubuntu 16.04 to 17.04, Linux Mint 17.x and 18.x
 sudo add-apt-repository ppa:nilarimogard/webupd8
 sudo apt update
 sudo apt install woeusb

<small>To create a Windows 7 boot:
* from console execute:
 sudo bash
 echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
 echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes
 exit
* ensure ISO is on the local disk, not a network drive or mounted from another medium, this seems to cause problems
* using an ISO, run WoeUSB, and select NTFS as the file system for the flash.  
* If you get an exit code 256 error after the NTFS format, dont worry.  Just start the process over.  It seems to be a conflict between automount and woeusb.  The second time around it starts copying files after it realizes the drive is NTFS formatted already
* monitor the progress from console with nmon

Note: This process is not verified, and failed during testing.</small>

=== Etcher / balena Etcher ===
* https://www.balena.io/etcher/
* Cross-platform (Windows, macOS, Linux) +  burn images on USB drives and Micro SD Cards.
balenaEtcher is a free and open-source utility used for writing image files such as .iso and .img files, as well as zipped folders onto storage media to create live SD cards and USB flash drives.  Uses a GUI Etcher Bootable USB Creator.

When I downloaded Etcher for Linux from the main web page the program came as an [[AppImage]] file.  They also provide external links to deb package and other options such as RPM.

=== The dd Command in Linux ===
* https://linuxize.com/post/create-bootable-debian-10-usb-stick-on-linux/
Here are some examples using dd.  
 sudo dd if=./linuxmint-19.2-cinnamon-64bit.iso of=/dev/sdc bs=4M status=progress oflag=sync
 sudo dd if=./linuxmint-19.2-cinnamon-64bit.iso of=/dev/sdc bs=4M status=progress conv=fdatasync
 sudo dd if=./linuxmint-19.2-cinnamon-64bit.iso of=/dev/sdc bs=4M && sync
These are from different sources.  Sometimes this works.  Sometimes it just sits there forever and you don't get a prompt back even if you try to break.

When you insert the USB flash drive into the Linux PC it is immediately recognized as a block device, not not necessarily auto mounted even when auto mount is enabled.  It will be auto mounted if there is a partition that has a compatible file system.  If it is auto mounted you need to unmount it from the command line while not "ejecting" it.  We want the kernel to see the block device, however, we do not want any partition mounted.  

The block device will show up in fdisk -l and if it does not, then you will not be able to write the ISO to the flash drive.  If the flash drive auto mounts, then simply unmount it by a command
 umount /dev/sdc
With the block device recognized, and the partition(s) not mounted, I found this command to work best:
 sudo dd if=./linuxmint-19.2-cinnamon-64bit.iso of=/dev/sdc bs=4M status=progress oflag=sync
can detach a USB drive with the following commands
 sudo eject /dev/sdc
After invoking the eject command the USB flash drive is no longer a block device visible with fdisk -l
