Once a bootable device with BackBox on it has been created, you are ready to try it out. This involves (re)booting your machine with the device inserted in it.

• CD/DVD drives usually have priority during boot, so if you burned BackBox Linux to a DVD, you can just boot with the disk in, and you should be welcomed by the BackBox bootloader screen. Yeah! That's it! If this is not the case, and your PC is still booting the OS installed on your main hard drive, you must select the DVD drive as boot device in your BIOS configuration screen, as explained in the next section.
• USB drives usually have a lower priority than the hard drive during the boot, so you must change the boot order in your BIOS configuration screen, as explained in the next section.

Boot the machine with the bootable device inserted, and enter the BIOS configuration screen with the appropriate key combo. This one is usually shown at the bottom of the screen in the early stage of the boot process and varies from machine to machine (common keys to enter the setup may be: one of the function keys (F1-F12), DEL, ESC etc.). Once you are in, you should be able to find a submenu that lets you alter the boot order of the detected devices. Set the BackBox bootable device as first device, and exit saving the changes (usually F10).

When the machine reboots, it should be able to select the right device and boot BackBox Linux.
