Ubuntu is the most popular Linux distribution till date. It is highly stable, quick, and can run on a system with just 2 GB RAM and 25 GB hard disk space. Ubuntu Live USB drive let’s you test drive Ubuntu without actually installing it on your computer. So no effect on system partitions. Later when you think Ubuntu is for you and can become a daily driver, you can use the same Live USB drive to install Ubuntu on your computer.
Create Ubuntu Desktop Live USB Drive
STEP 1: Get an empty USB flash drive of at least 2 GB capacity. I don’t recommend not more than 8 GB because not all PCs can boot through USB drives of more than 8 GB capacity.
STEP 2: Download Rufus utility for Windows. It is a free portable utility and so doesn’t need installation. You can execute the program right away.Download Rufus
STEP 3: Download the latest version of Ubuntu Desktop from their website. Again, this is also 100% free operating system. The downloaded file will be in ISO format. The downloaded ISO should look something like this: ubuntu-16.04.1-desktop-amd64.iso. The version number may vary depending on when you are downloading.
STEP 4: Right-click on the downloaded Rufus program and click ‘Run as Administrator’.
STEP 5: Rufus Settings:
(#1) Click on the CD drive icon near the check box ‘Create a bootable disk using ISO Image’ and select the Ubuntu ISO file that you downloaded, for example mine says ubuntu-16.04.1-desktop-amd64.iso.
(#2) In the same interface, click on drop-down list under ‘Partition scheme and target system type’, select ‘MBR partition scheme for BIOS or UEFI’.
(#3) Next select file system as ‘FAT32’.
(#4) Finally click ‘Start’.
STEP 6: Keep the ISO Image mode to write when prompted and click OK.
STEP 7: Wait until Rufus writes the data to the USB flash drive.
That’s it. Your Ubuntu Desktop Live USB drive is ready! You can boot into it and test drive it. It also serves as a installation media just in case you decided to install it.
