In order to create a bootable USB which you can use for the installation you will need three things:
In this tutorial all files will be stored on the desktop
Download the desired ISO file.
If you have anything valuable on this USB flash drive, store this data on another device or computer. All files will be wiped during the process.
If you are using Windows older than 7 (XP or Vista) then you must use Rufus 2.18 as Rufus from version 3 up will not work on older operating systems.
Under “Device” you need to select your Flash Drive PARTITION
SCHEME For older computers (pre Win 8) select MBR partition
for BIOS For newer computers select GPT
FORMAT OPTIONS Make sure that the boxes are ticked as in the
picture and ISO Image is selected from the drop down men
It will open up next window in which you need to navigate to the location of the downloaded ISO file (in this case the ISO file is located on the desktop)
Highlight the ISO file and press “Open”
