Looks like your BIOS is capable only of booting from the first CD-ROM
device. Your BIOS cannot boot from your second CD-ROM device (your DVD-RW
drive).
You will need to re-connect and re-jumper everything so that your DVD-RW is
the first CD-ROM device that your BIOS sees.

Grub has nothing to do with booting from a CD-ROM. Grub's only purpose is
to bootstrap your kernel and initrd.
