Use Unetbootin to create a USB flash drive to load the Linux System

Use Unetbootin to create a USB flash drive to load the Linux System

Maybe you have heard of Linux and are a little curious about it. You finally want to try it out, but you may not know where to start.

It is very likely that you have searched for some information on the Internet, and then encountered some words like dual systems and virtual machines. They may be too professional for you, so you won't sacrifice the operating system you are using just to try Linux. What should we do?

If you have a USB flash drive in your hand, try a USB Linux boot disk. It is a USB flash drive that includes the entire operating system and can be directly booted. Creating it does not require any technical expertise. Let's take a look at how it works and how to boot from USB to Linux.

What you need to prepare

In addition to a desktop or laptop, you also need:

• A blank USB flash drive-preferably with a capacity of 4 GB or more.
• An ISO image of the Linux release you want to try (an archive file that packs all the disk content ). I will introduce it in detail later.
• A Unetbootin application is an open-source, cross-platform tool used to create a USB boot disk. You do not need to start Linux to run it. In the following tutorial, I am running Unetbootiin on a MacBook (LCTT Note: it also has Windows and Linux versions ).

Start working

Insert the USB flash drive to the USB port of your computer and start Unetbootin. Then you will be asked to enter the login password of the current computer.

Do you still remember the ISO image file mentioned earlier? There are two ways to get this: either download it from the Linux release website you want to try, or ask Unetbootin to download it for you. If you select the latter, click Select release version at the top of the window, select the release version you want to download, and then click Select version to select the release version you want to try.

Alternatively, you can download the release version by yourself. Generally, the Linux release I want to try is not in the list. If you select to download the image, click the disk image and then click the button to select the. iso file you downloaded.

Note that the following options reserve the space for saving files after each restart (only valid for Ubuntu? If you are trying Ubuntu or any of its derivative versions (such as Lubuntu or Xubuntu), you can leave a few MB space on the USB flash drive to save files, for example, webpage bookmarks or documents you have created. When you use this USB flash drive to start Ubuntu next time, you can continue to use these files.

After loading the ISO image, click OK. Unetbootin may take less than 10 minutes to create a USB boot disk.

Test the USB boot disk

At this time, you need to embrace your inner geek spirit. This is not too difficult, but you will need to enter the BIOS to peek at the internal space of your computer. The BIOS of your computer loads various hardware and controls the boot or startup of the computer's operating system.

BIOS usually searches for the operating system (or in a similar order) in this order: hard disk, CD/DVD drive, and external storage device. You need to adjust this order to make the external storage device (here, it refers to your USB flash drive) the first device to be searched by BIOS.

To do this, insert the USB flash drive into the computer and restart the computer. After you see the message Press F2 to enter setup, follow the instructions. On some computers, this key may be F10.

In BIOS, use the right arrow key on the keyboard to switch to the Boot menu. Then you will see the drive list on your computer. Use the downward arrow key on the keyboard to select the option named usb hdd, and press F6 to move this option to the top of the list.

After that, press F10 to save the changes. Then you will be kicked out of the BIOS, and the computer will start on its own. For a moment, you will see a Startup menu for the Linux release you are trying. Select Run without installing (or the most similar option ).

After entering the desktop, you can connect to a wireless or wired network, view the web page, and try the pre-installed software. You can also check whether your printer or scanner works properly under the release you are trying. If you really cannot think about it, you can also touch the command line.

What can I do?

Based on the speed of the Linux release you are trying and the USB flash drive you are using, the operating system may take a long time to load, and it may be a little slower than loading it directly to the hard disk.

In addition, you can only run the basic software pre-installed in the Linux release. Usually there will be a Web browser, a text processing software, a text editor, a media player, a photo browser, and a set of practical tools. These should be enough to give you the feeling of using Linux.

If you decide to use Linux, you can double-click the installer to install it from the USB flash disk to the hard disk.
