How to boot from a CD, DVD or BD

1. Change the boot order in the BIOS to CD or DVD appears first. Some teams are already configured in this way, but many are not.

If the optical drive is not the first in the boot order, your PC starts “normally” (ie, the beginning of your hard drive) without even looking at what might be in the player.

Note: After setting the optical drive as the first boot device in the BIOS, the computer will verify that the training shoe every time the computer starts. Leave your PC configured in this way should not cause problems unless you intend to leave a disc in the player all the time.
