Creating a bootable flash drive
The process of creating a bootable USB flash drive with which to install Ubuntu used to vary greatly between platforms. The steps were very different depending on whether your workstation or laptop was currently running Linux, Windows, or macOS. Thankfully, a much simpler method has come about. Nowadays, I recommend the use of Etcher to create your bootable media. Etcher is fantastic in that it abstracts the method such that it is the same regardless of which operating system you use, and it distills the process to its most simple form.
Another feature I like is that Etcher is safe; it prevents you from destroying your current operating system in the process of mastering your bootable media. In the past, you’d use tools like the dd command on Linux to write an ISO file to a flash drive. However, if you set up the dd command incorrectly, you could effectively write the ISO file over your current operating system and wipe your entire hard drive...
