Computer literate people need your help. My hard disk crashed and my DVD/CD drive isn't working .....? - hard drive boot disk dvd players and drives

My model crashed recently and so I bought a new hard drive, but my CD-ROM was not previously worked, so I installed a new DVD player as well. Will I be able to start the operating system if I install a new DVD? Can I boot the operating system from the DVD?
