When USB drives came to market, it was said that it will replace CD because there were lots of advantages of USB drives on CDs. They need lesser space to carry; you can delete data from it and store a new one, and they have faster reading and writing speed. This one thing still beats USB drives that you can install Windows OS and Linux OS only using a CD. But now things have changed, you can now install any OS from the USB drive by making your flash drive Bootable.
There are lots of freeware on the internet which can make your drive bootable and then you can boot any OS from it (except Mac OS).
- A USB drive with at least 4 GB space (8 GB recommended).
- OS image file (ISO file).
Rufus (Free | Windows):
Rufus is a freeware with which you can create a bootable drive of almost all OS available. Rufus is available in two versions portable and installer. The portable version is a standalone executable file which you can launch from anywhere it is saved on your PC, and the installer version will get installed on your PC, this is no performance difference between them. Below are the steps to create a bootable USB drive using Rufus.
- Launch Rufus on your PC.
- Select your USB drive under “Device” section.
- Click on the CD drive icon under the “Format option” and select the ISO file.
- Finally, click on “Start” button.
- Rufus will start copying the files from the ISO file (this will format the drive and all data on the drive will be erased).
- After some time, Rufus will notify you about the completion of the process.

UNebootin (Free | Windows, Linux, Mac):
UNebootin is the best freeware for making the bootable drive for Linux. UNebootin is also a standalone tool, but the best part of the UNebootin is that you don’t need to download the image files separately, UNebootin is built with the feature to directly download the OS and make your drive bootable. UNebootin creates live USB so you can try the OS without actually installing it on your PC, this feature is restricted to Linux-based OS only like Android, BackTrack, Kali Linux and more. To make your drive bootable using UNebootin just follow the steps below:
