Normally, the conversion is not necessary, and what you should do is to create a partition and format it on which you create a DOS system.

The best freeware tools for bootable USB drives: An overview

Instead, the operating system is either preinstalled on the system partition of a new computer or laptop, or you acquire Windows directly online, complete with a digital license, and download it yourself.

But if you need an external installation medium, many people nowadays use a bootable USB drive. It’s quicker and more compact that an optical data carrier, and so is perfectly suited for setting up (or resetting) a system – there are also many other possible uses.

There are lots of uses for a bootable USB drive. The most important is, of course, booting the PC if it will no longer start itself because of a virus, serious system failure, defective hard drive, or partition problems.

The small piece of hardware is the standard solution for hosting an entire operating system and/or a recovery system like the multi-virus scanner Sardu and using it to successfully reboot and repair the computer.


  • In addition to various other tools, Sardu also contains 20 virus scanners that can search the entire hard drive of a defective computer for malware and clean it up. Even if no such PC emergency is present, it’s a good idea to have a Windows image for data backup on a USB-capable storage medium (could also be an external hard drive) on hand. You can also use a bootable USB to upgrade Windows 7 or 8 to Windows 10 if a previously automatic upgrade doesn’t function correctly.

  • Store an image of the operating system.
  • Upgrade an old operating system to Windows 10.
  • “Clean” reinstallation of the operating system.
If you are a developer, you are very much encouraged to tinker with Rufus and submit patches.


Since I'm getting asked about this on regular basis, there is no donation button on this page.

The main reason is that I feel that the donation system doesn't actually help software development and worse, can be guilt-inducing for users who choose not to donate.

Instead, I think that "mécénat"; or developer patronage, from companies which benefit most from a healthy FLOSS ecosystem, is what we should be aiming for. This is because, unless they are backed by a company, developers who want to provide quality Open Source software cannot realistically sustain full time development, no matter how generous their software users are.

Also, unless you are blocking them (hint, hint), you'll notice that there are ads on this page, which I consider sufficient revenue enough.

Finally the fact that I have the freedom to develop Free Software in my spare time should indicate that I'm well-off enough, and therefore that you should direct your generosity towards people who need it a lot more than I do. If you really insist, you can always make a donation to the Free Software Foundation, as they are the main reason software like Rufus is possible.

At any rate, I'll take this opportunity to say thank you for your continuing support and enthusiasm about this little program: it is much appreciated!

But please continue to feel free to use Rufus without any guilt about not contributing for it financially – you should never have to!
