If you are unsure how to write an ISO to a USB flash drive, this guide will show you how to use Rufus. Many modern systems do not include an internal optical drive and require a USB flash drive to boot unless you use a USB optical drive. This is especially common on modern laptops and some desktops where it is an option and not standard. Using a USB drive is often a more practical workaround for these systems. A 16-32GB* USB flash drive is generally easier to set up and use outside of DVD-only applications or situations.
TL;DR: When buying new, 32GB+ (USB3 preferred, USB2 "works" but will be slow).
IF YOUR BUDGET IS THIN, FORMAT AN OLD DRIVE YOU CAN ERASE IF YOU ARE CHOOSING BETWEEN NO NAME JUNK OR A KNOWN NAME BRAND!
*Older low-capacity drives, such as an 8GB USB drive, will "work," but you will have limited spare space for files and NF firmware you may need (E.g., Intel wireless cards, nVidia graphics). Generally, 8GB drives are no longer available "new" but are sometimes found in generic bulk packs priced to be disposable ("no name" drives). IN GENERAL, the current recommendation for buying a new drive is to purchase a 32GB drive (USB3 preferred, USB2 drives are slow) at the bare minimum, and ~$1-2 USD cheaper than most 64GB drives. While you can still find 16GB drives, they are generally only sold as rebranded Chinese drives (such as Onn), generics, or from "hole in a wall" companies. While these may work, you do not save much (average $5 or less), so they are not recommended. You are generally better off formatting an older name brand 8-16GB USB drive you have over purchasing a generic drive 9/10 times.
READ: Important note about legacy operating systems.
Important: OSes without explicit USB boot support are not guaranteed to work. While the risk is low with the right tools, I cannot guarantee anything. You are on your own if there are unforeseen issues with ancient operating systems.
This guide was initially written exclusively for Linux. However, any relatively modern operating system released in the past ~10-15 years can generally be booted from USB.
Guide notes
- Used drives should ideally be erased before formatting in Rufus.

Unetbootin does not work anymore and is considered unstable to use when installing any Linux OS, also 4GB USB drives are more than big enough to get the job done
My reasoning for saying 8GB is because 4GB sticks are all but nonexistent (8GB is more popular now), but if you already own the 4GB stick then it'll work. I even use one from 2006 in the guide, to show that reuse is possible.
Oh really? I always thought it was still a usable option - thanks for letting me know that I was wrong.
