If you don't have a boot menu option like F11, you will have to enter the bios and go to the boot sequence page. There you need to set the cd rom/ dvd as the number one boot device. Press F10 to save your changes. When boot up begins, press the spacebar when you see "Press a key to boot from cd".
Now you will be able to enter the recovery console.
