How to Install Ubuntu from USB?

The Ubuntu operating system does not need additional popularization. This is one of the most famous GNU/Linux distributions developed by Canonical. It has a beautiful interface (both by default and with other desktop environments) and convenient functionality. This article describes how to install Ubuntu via USB Flash drive.

System Requirements

For the comfortable operation of the system, you must have at least the following computer characteristics:

  • 4 GB of RAM;
  • Dual core processor with a frequency of 1.6 GHz;
  • Video adapter with 32 MB VRAM;
  • 30 GB of free disk space.

A little explanation. RAM needs at least 4 GB, as the company officially discontinued the release of 32-bit systems and deals only with 64-bit. And for the normal functioning of such a system, you need 4 GB or more of RAM. Some community edition systems also release 32-bit systems, but you have to use them at your own risk.

As for free disk space, here 30 GB is an extreme minimum. After installation, the system itself will occupy about 6–8 GB, but user data, additional programs, caching, etc. will always take up more space. As practice shows, during normal operation of the system, at least 50 GB are required.

Step 1. Preparing for Installation

If you are going to install Ubuntu on a clean disk, you do not have to do any additional procedures before starting the installation. If on the computer there is another OS (for example, Windows 10), then you should allocate a separate section for Ubuntu on the disk. Then, on the Ubuntu website, you need to download the distribution of the desired version, write it to the USB flash drive and start from it after the POST test.

Choosing options for encrypting a partition or using LVM depends on your knowledge of these issues. If you are not sure what you need, do not mark these items.
