Go in to your BIOS and manually choose the disk drive. Don't choose the disk drive as the primary boot and then restart the PC.

The boot device menu for Lenovos is usually F8, F10, or F12. Try holding one of those down as you turn on the computer. When you get the right one, you should get a short menu of all devices the computer can boot off of. Select the DVD. There's no need to change the boot order in the BIOS.
