About This Tutorial

Practicing this tutorial will help you

• install Ubuntu into a blank USB flash disk drive, then as a consequence:
• it is safer, less risky to your existing Windows and data if any, and
  
• dualboot made automatically with Windows if any, and
• give you ability to be nomaden or portable, that is, the Ubuntu flash drive can run on different computers and laptops while all data stored inside it, and
  
• you can adapt this to install Ubuntu normally into HDD, or
• into external HDD, or
• into SSD.
  

Requirements

- 1 x PC or laptop. 

- Either BIOS Legacy or UEFI system in the computer.

- 1 x USB flash drive >= 4GB (we call this "bootable").

- 1 x new empty USB flash drive >= 16GB  (we call this "target"). (*)

- 1 x Ubuntu Desktop 22.04 LTS image file.

For example, to write this tutorial we actually install Ubuntu 22.04 into Lenovo ThinkPad T430 (laptop), a 16GB flash drive (as bootable), a 32GB flash drive (as target), and Ubuntu 22.04 (as the operating system). Internet access is not required.

(*) We strongly suggest you to get a new USB flash drive and not using a used one. It is still cheaper than hard disk drive.

Ubuntu Preinstalled Laptops

We always want to share that today we saw many computer vendors who sell PCs and laptops with Ubuntu preinstalled so now you can buy a branded one with Ubuntu and not Windows. Today we know the vendors who already offer Jammy Jellyfish are StarLabs, LaptopWithLinux, and TUXEDO from Europe you can order worldwide. Aside from it, to install Ubuntu by yourself, please follow the rest of this tutorial.
