Share me please

When do we need bootable Ubuntu usb pendrive?

There are some moments in developer’s world that we need to have fully bootable USB pendrive with any kind of linux distribution. In this article I will show you how to prepare pendrive with Ubuntu 18.04 distribution. This skill may be especially worthy for you when:

  • some virus will inject your operating system like Windows and you cannot boot it in a standard way
  • you want to upgrade existing distribution of linux
  • you don’t have CD-ROM in your computer but you need to install ubuntu distribution of linux

Preparing ISO file with Ubuntu 18.04

The starting point in preparating the usb pendrive with ubuntu will be to find the interesting you ISO image of linux in the Internet.

This is very easy task. Just type the phrase like ‘Ubuntu 18.04 iso download’ in google search engine and you should get in your first results the correct link. For me it is: http://releases.ubuntu.com/18.04

Download the file with iso. You need to be prepared with enough space in your disk that oscillates around 2GB for iso file and around 4GB of size in your pendrive. For all modern PC stations/notebooks this probably is not any problem to have such free space on your disk 🙂

Getting Rufus tool to “burn” your Ubuntu

When you downloaded ubuntu linux iso image file you need to download a special tool named Rufus. This tool was created specially for burning any kind of iso image files into CD-ROM plates or usb systems as a bootable system.

You can start downloading the tool from website: https://rufus.ie/. This is relatively light tool that takes only 1.1 MB of free space on your disk. Do you remember the days when this space was available only on floppy disks ?

What is good you don’t even install the tool when you download portable version of rufus. You can decide what is more convenient for you.

Running Rufus tool to burn Ubuntu iso file

You have installed Rufus application. You can run it but before you will do it let’s mount your usb pendrive into your PC. Verify that usb stick is correctly installed in the system. If there is now problem with it we can start configuring Rufus tool.

In order to properly configure the tool you need to do two actions only:

  • select your usb stick from the list of devices
  • click button Select and select ubuntu iso file that we previously downloaded from the Internet

All the rest options leave as they are. Finally click the button Start and this will run the whole process of installing Ubuntu on your usb pendrive. You may be asked about downloading additional files during the whole process. Hit Yes button to accept the request.

During the installation process you should also see the window ISOHybrid image detected. Accept default option ‘Write in ISO Image mode’ which is recommended option.

Some seconds later you will have fully installed Ubuntu 18.04 operating system on usb stick. You can start using this for booting damaged operating systems or making any updates.
