Yes but it is not hard. When you boot up look to the bottom left of the screen. When you see DEL hit delete. This will take you into the bios. Be very careful in there. Use the enter, Esc & arrow keys to navigate. Look for the option where you can change the boot order & make the cd rom boot first. Don't worry if you are not sure you can exit bios by choosing 'exit without saving'. That will leave things as they now are.
