Exit the BIOS
Follow guidelines to exit out of your BIOS and save your modifications.

Depending upon your BIOS, you might need to confirm your choice again.

Reboot
Your computer system needs to reboot instantly. Make certain your CD or USB drive remains in your computer system. If you’re prompted to “Press any essential to boot from external gadget”, do so. Your computer system needs to boot into the CD or USB drive instead of your regular operating system.

You must see icons for your available drives. On the right, you’ll discover your external (CD or USB) drive with its name listed beneath. Utilize your arrow secrets or your mouse to highlight that drive, then press Return or click on the arrow below it.
