Bootable USB vs. Portable USB: What's the Difference?

Do a bootable, and portable USB drive concept confuse you? Then, you aren't the only one who can't tell the difference between bootable and portable USBs. Often people peg both for the same, but that's untrue. 

Both bootable and portable USBs are useful in different situations. 

Bootable USB or other external devices contain a bootable program that can take control of the computer. Usually, Windows ISO files are stored in bootable USB drives to initiate a clean operating system install. A bootable USB is useful to recover your failed system. 

Portable USB also carries OS frameworks, but it isn't required to install them on the computer. By simply inserting a portable USB drive into a computer, one can run OS stored in the USB on any device. 

The portable USB drives are extremely helpful to run Windows-specific games or applications on Mac devices. You can simply clone the entire system on a portable USB and make it bootable on other devices. 

Now that it's clear, what a bootable and portable USB drive is, next, let's see how to create them. 

And that leads us to the topic of the hour, Rufus vs. EaseUS OS2Go. Rufus is a robust tool to create a bootable USB drive, and EaseUS OS2Go is a powerful program to create a portable/bootable USB drive. Let's explore both programs in detail.
