Sometimes CD/DVDs are referred to as Optical Drives (ODDs). Or it may be faulty or disabled in BIOS.
Was it a business laptop?
Check BIOS for any restrictions. Disable Secure Boot. Enable any legacy mode or MBR (instead of UEFI) options if you have them.
If you still can't boot from CD/DVD you can try booting from USB Flash.
On a working computer...
Make an iso file from Windows DVD. Use Imgburn to do this.
(A lot of Freeware comes with unwanted stuff now. Install Unchecky first to aid not installing junk by mistake)
Use Rufus to burn the iso to Flash Drive (8GB+)
When done, power down the laptop, insert USB Flash and reboot. (USB priority must be higher than HDD)
