You can boot directly from a Live DVD or USB. Usually, you just need to plug the USB device in or place the DVD in the drive and restart the computer. If the computer does not automatically boot from the USB or DVD you may need to reconfigure your BIOS Boot Disk priority. Alternatively, you might try accessing the boot device menu to select a device from which the computer will boot. To access the BIOS or boot menu when the computer is starting, you can try pressing either F2, Del or Esc for the BIOS, or Esc, F8, F10 or F11 for the boot device menu. These (fairly common) keys are just a selection of possible options though. The actual screen that you will first see when booting from the Live media will depend on whether your computer motherboard is of the Legacy (BIOS) or UEFI type.
