Once you have downloaded Ubuntu image and Rufus, it is time to create the bootable USB drive.

So launch Rufus and insert the USB stick. Rufus will identify the USB and update the device drop down to show it. If device is not correctly identified you can change it manually to point to the correct device.

For “partition scheme and target system type” drop down select “MBR partition scheme for UEFI” option if you have a newer hardware with UEFI. Alternatively you can select “MBR partition scheme for BIOS or UEFI”.

For selecting the downloaded Ubuntu iso image click on the optical device symbol which is on the right side of the check box option “create a bootable disk using”. Select the downloaded Ubuntu iso image.
