Do you want to try a new Linux distribution? Your old computer does not start because of the corrupt file system or it’s infected by a virus or you bought a new computer. If you’re in any of the above situations then you will need to install a new operating system on your computer. Although you can make bootable USB flash drive in a variety of ways using different tools. In this tutorial, we’re going to make a bootable USB flash drive using Rufus.
Download the latest version of Rufus portable from rufus.ie. Download the ISO image of the operating system that you want to install. Also, make sure you have an empty USB flash drive with a size of at least 4 GB, you will need a USB flash drive of 8 GB if you’re using windows image.
3. Create bootbale USB
Insert the pen drive to your computer and open Rufus. You’ll see the following Rufus screen. At the top of the screen under Device make sure your USB flash drive is selected. Below Device under Boot Selection select Disk or ISO image and click on the select button right to select the ISO image as shown below.
Select the ISO image you downloaded. Here I have selected Ubuntu 20.04 ISO image. If the target device disk is partitioned as MBR you can click start and wait for the files to be written to USB flash drive.
But if your target device disk is partitioned using GPT you’ll have to select GPT under Partition scheme as shown.
If you’re going to completely format the target device you can select either GPT or MBR, but while creating a new partition table you’ll have to create the partition table of the same.
If you want to use the USB flash drive itself like installation disk and don’t want to install the operating system in your hard disk. You’ll have to enable persistent partition. You can select the persistent storage size by changing the slider under Persistent partition size as shown( note this works for Linux ISO only).
After clicking start you might be presented with a write mode selection screen as shown below, just click ok and continue.
Now, wait for the files to be written to a USB flash drive. This usually takes a while.
After all the files are copied click close, you’re now ready to install the operating system to your computer or use the flash drive itself to boot the system and test.
You have successfully created the bootable USB flash drive using Rufus in windows. You can use this same method to make a bootable USB drive of Linux, Windows, BSD, or UNIX OS. Now if you want to install the operating system on your computer, you can look at this Ubuntu Desktop 20.04 (Focal Fossa) installation guide.
