How to Download and Use a Live OS
A live OS is an operating system that runs directly from a removable storage device such as a USB flash drive or a DVD, without installing it on the computer's hard drive. A live OS can be used for various purposes, such as testing, troubleshooting, data recovery, privacy, security, or simply trying out a different operating system without affecting your existing one.

In this article, we will show you how to download and use a live OS. We will also discuss some of the advantages and disadvantages of using a live OS.
What is a Live OS and Why Use It?
A live OS is a complete bootable computer installation that includes an operating system and some applications. It runs entirely from RAM, which means it does not write any data to the storage device it is loaded from. This makes it faster and more secure than a regular operating system that runs from a hard drive.
There are many reasons why you might want to use a live OS. Some of them are:
Portability: You can carry your preferred operating system, applications, configuration, and personal files with you on a small device and use it on any compatible computer.
Privacy: You can work with sensitive documents or browse the internet without leaving any traces on the computer's hard drive or online. You can also encrypt your data and settings on the storage device for extra protection.
Security: You can avoid malware, viruses, spyware, and other threats that might infect your regular operating system. You can also update your live OS regularly with security patches and fixes.
Testing: You can try out different operating systems or software without installing them or making any changes to your computer's configuration. You can also test how your computer performs under different conditions.
Recovery: You can use a live OS to access your files or repair your system if your regular operating system fails to boot or gets corrupted.
Some examples of live OS are:
: One of the most popular Linux distributions that offers a user-friendly interface and a large collection of software.
: A Linux distribution that focuses on preserving privacy and anonymity by routing all internet traffic through Tor.
: A feature of Windows 8 Enterprise and Windows 10 Enterprise that allows you to create a portable version of Windows on a USB drive.
: An Android-based operating system that lets you run Android apps and games on your PC.
How to Download a Live OS
The first step to use a live OS is to download it from its official website or a trusted source. The next step is to create a bootable USB or DVD with the live OS that you downloaded. This will allow you to start your computer from the live OS without installing it on your hard drive. To create a bootable USB or DVD, you will need a tool that can write the ISO file to the USB or DVD in a way that makes it bootable. There are many tools available for this purpose, but some of the most popular ones are:

To use any of these tools, you will need to follow these general steps:
Download and install the tool of your choice on your computer.
Insert a USB flash drive or a DVD into your computer. Make sure it has enough space and is formatted correctly. Note that all the data on the USB or DVD will be erased during the process.
Launch the tool and select the ISO file of the live OS that you downloaded.
Select the USB or DVD as the target device to write the ISO file to.
Click the button to start the process and wait for it to finish.
Once the process is done, you will have a bootable USB or DVD with the live OS on it. You can now use it to boot your computer from the live OS.
How to Boot from the Live OS
To boot from the live OS, you will need to insert the USB or DVD into the computer and restart it. However, simply restarting your computer may not be enough, as it may still try to boot from your hard drive by default. To change this, you will need to access the boot menu or the UEFI/BIOS settings of your computer and select the USB or DVD as the first boot device. The exact steps to do this may vary depending on your computer model and manufacturer, but here are some general guidelines:
To access the boot menu, you will need to press a specific key right after you turn on your computer, before Windows starts loading. The key may be different for different computers, but some common ones are F2, F9, F10, F12, Esc, or Del. You may see a message on your screen indicating which key to press.
To access the UEFI/BIOS settings, you will need to press another specific key right after you turn on your computer, before Windows starts loading. The key may be different for different computers, but some common ones are F1, F2, F10, Del, or Esc. You may see a message on your screen indicating which key to press.
Once you access the boot menu or the UEFI/BIOS settings, look for an option that lets you choose the boot device or change the boot order. Select the USB or DVD as the first boot device and save your changes.
After you have changed the boot device or order, restart your computer and it should boot from the live OS. You will see a welcome screen where you can choose your language and other options. You can then click on Try Ubuntu (or Try [name of live OS]) to start using it without installing it on your hard drive.
