Yes you can, but only if the BIOS setting permits it. If it doesn't do it automatically you will have to check the "Boot devices" settings and make sure CD-ROM comes first in the list. You can check the BIOS settings at the point when you boot up the PC after it has been switched off. Switch on the PC and then, during the boot-up phase, you must keep holding down the 'Delete' key until the BIOS settings screen is displayed. Then find the "Boot devices screen" and use the 'Page Up' and 'Page Down' keys to ensure that "Boot from CD-ROM" appears 1st in the list and the Hard Disk appears 2nd in the list. Then save the settings and allow the PC to reboot. It will then check if there is a CD-ROM inserted in the drive. If there is a CD-ROM there it will try to boot from it. If you have made the PC's 2nd boot device the Hard Disk then, if there is no CD-ROM in the drive, the PC will go to the the Hard Disk to boot up. All that will happen automatically every time the PC is rebooted.
