What is a Rufuss USB Installer?

Rufus is a very useful utility and if you do not have it, you should get it in your toolbox.

Rufus creates a bootable USB stick (/drive) which can be used for installing, for example UBUNTU Linux.

Rufus formats and creates a bootable USB drive to which you can attach memory sticks, pen drives, etc.

These are some of the use cases (rufus.akeo.ie):

• You need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.)
• You need to work on a system that doesn't have an OS installed
• You need to flash a BIOS or other firmware from DOS
• You want to run a low-level utility

Rufus is supported by many operating systems.

Download these executables from the link at the beginning of this post.

I downloaded both but ran the 2.11.exe and it made entries in the Registry.

I am planning to work with Ubuntu Linux in my Windows 10 laptop and this is just a preparatory step.
