Your BIOS is probably not set to boot from a CD-ROM. Luckily I have the same laptop so if you press and hold the "c" key when it boots up and keep holding it until it beeps at you it will then boot from a cd. You could also press esc and go into the BIOS if you're adventurous.

Check with someone you know to see if they have a USB external CD or DVD drive that you can borrow. Then set it to boot from USB. There is also a possiblity that you have a corrupt CMOS fireware. See if you can download an BIOS firmware update and place it on a external floppy and install. Good Luck
