Linux USB


Linux USB is about using a Linux open source operating system, to boot from a USB flash drive. This USB drive enables users to have a portable Linux OS, supporting apps and personal settings with them and run the OS from any computer that can boot from a USB drive. Linux USB can also refer to the USB driver support of Linux for the three main USB standards, USB 1.1, 2.0 and 3.0.

How to install and boot Linux with USB

First, you need a universal USB installer (, which is a "Live Linux USB Creator" and you can read more about at the Wikipedia Live USB article.
After downloading it, the Universal USB Installer ( above) is installed. Then this universal USB Installer is used to make your Linux USB boot drive.
(OS booting with USB flash drivers, means that an operational system can be launced, similar to LiveCD, called LiveUSB.)

You also need the Linux ISO file to be on the a USB drive. Popular distribution sources of Linux are Fedora, Ubuntu (with variants) and Mint.

Set the USB flash drive into your computer and then open the "installer." From the drop-down menu, you Choose which Linux distribution you want to run and then browse to the downloaded ISO file you on the ISO drop-down menu. Then, select the letter designation for your USB drive. You see a "Create" button which you press, which allows your machine to create the bootable USB drive. Windows XP, Vista or 7 is required for this tool to work properly. Older versions of Windows can't be used.

By using Your Universal Multiboot Installer or YUMI for Windows machines you create your Linux Live USB.

With YUMI you can install several different Linux distributions to the same USB flash drive, so that you may test lots of Linux distributions before settling on one. You can also install all of your Linux recovery tools for other computers to one portable place.

Download and install YUMI and the ISO file for the Linux distribution you would like to use on your USB drive. The USB flash drive is put into a USB port. Then run YUMI. From the drop-down menu, choose the drive letter of your USB drive. If not already formatted to FAT32, check the box to format the drive.

If another distribution is added to the USB drive, do not check this box. The distribution you want to install from the list is chosen, then browse to the location of the downloaded ISO file. Push the "Create" button and allow YUMI to format and build the Linux Live USB. Windows XP or higher operating systems is required for the YUMI tool.

With the Shardana Antivirus Rescue Disk Utility or SARDU, you build a Multiboot Linux USB. SARDU tool is downloaded from the manufacturer's website, and install it on a Windows machine. From the distribution websites, it can directly download the ISO files, so there is no need to go looking for them yourself with this tool. Launch the tool where to click the tab labeled "Linux Live." Next to the Linux distributions you want on the Live USB drive, Check the boxes and choose the USB drive letter from the drop-down menu.
Push the USB flash drive icon-buttononand the tool to create your USB drive. Install a specific popular Linux distribution using a web-based tool on their website. Ubuntu and Fedora, for example, have web-based tools that properly format the bootable ISO files so they can be installed and run from USB flash drives. Go to the website for the Linux distribution you want to use and follow the specific online instructions for downloading the appropriate files and installing them onto the USB drive. There is no minimum requirements for the operating system for these tools. They only require an Internet connection and a web browser. This option is also available for creating a Linux Live USB on a Mac.

Now if you want more information, which is very likely, you would probably do some searches, such as for "linux usb installation", "installing linux usb" or "boot linux usb" etc. Ubuntu is often used on sites with installation advice.

Choice of USB flash drive

Of course, since an USB is used also for several reasons, there are some basic factors to consider.

1. The Gb size
2. Write times
3. Read times
4. Type of enclosure
5. write-protection switch
6. Durability and quality

Today, at least 16Gb is standard and shorter write and read times will save a little time. It's important that the housing, or enclosure is well built.
Some few USB flash drives have a write-protect switch, usually on the driver's housing. The USB flash driver can then be used for repairing virus-contaminated PCs without infecting the flash device itself.

There are several general advantages of USB drives, such as for PC software repair, where USB flash drives are excellent carriers of recovery and anti-virus software to infected PCs. For that reason, it is wise to have more than one USB drive.
