You mean the dvd or usb stick will not boot and you think that by adding an entry on the mainsystem's grub? If it is a bios booting system do you know the procedure or setup of booting other than from HD? In most systems F12 during bios reading gives you the option, on some HPs it is escF9, and there are a few other commands for different manufacturers. But I don't understand why you would want grub to be configured to boot a dvd. As Thomas says if it is an uefi system you need an appropriate iso. If it is a bios system it is bios that tells the system to boot from a specific medium, not grub. Grub comes up when bios tells the system to boot from hd and not a dvd or other medium.
