If a machine boots successfully from a CD or DVD or USB stick, or any other external device, no attempt is made to boot from the hard drive.
To boot from another device, that device must be working, must contain a bootable image, and the machine's BIOS must be set to attempt to boot from the device before it attempts any other devices. E.g., if you have a bootable Linux system on a hard drive, and try to boot from an unbootable DVD or try to boot from a faulty CD/DVD drive, the BIOS will transparently roll over and boot from the hard drive.
Since the machine can boot from a CD but is not booting from a Windows DVD, and assuming you are using a DVD drive, then the DVD must have a problem. Look for scratches; try a gentle cleaning.
