How to enter and exit the BIOS or CMOS setup.

When the installer boots successfully, you will see the Ubuntu loading screen. If it doesn't, change your computer's boot device sequence in your BIOS setup so your USB (or DVD-R) is ordered above your hard drive. The Ubuntu installer should start instead of Windows.

Reboot your computer with the USB flash drive (or DVD-R) inserted in your computer.

If you boot your computer while the disk is inserted, the installer runs.

Your flash drive or DVD-R should now be a bootable Ubuntu disk. When it does, you can exit by clicking Close. Look for the progress bar to complete, and the status message to say READY.

Keep an eye on the green progress bar, because there is no special message when the job is done.

To begin writing the image to your flash drive, click OK.

ISO image mode is the safer option because it does not overwrite the partition table on your flash drive.

The Ubuntu installer is an ISOHybrid image, so you will be given the choice of ISO or DD image writing mode.

If prompted, click Yes to download the updates.

At this point, Rufus may need to download updated SysLinux files.

Make sure your USB flash drive (or DVD-R drive) is selected in the Device drop-down box.

In the Rufus window, click the Select Image button (pictured) to choose an image file.

When you receive a UAC prompt, click Yes to continue.

Insert your flash drive into a USB port on your computer, or insert a blank DVD-R disk into your DVD-R drive.

Go to the Rufus site and download the installer. We recommend using Rufus Portable, a free utility for Windows. You'll need special software to create the bootable installation media.ISO image to a USB flash drive (or a DVD-R if you prefer). The size of the file will be about 1.5 gigabytes. To get it, go to the official download site and download Ubuntu Desktop. It's called an 'image' because it's a snapshot of everything that needs to go on an entire disk, all in one ISO file.
