HEHE no one answered you there ^^ Well...
Do try in Windows: Go into "My Computer" and right-click on your optical drive and "eject".
Or do try a live Linux CD/DVD, like this one:
http://www.ubuntu.com/download/ubuntu/download
You just have to download whatever ubuntu version you want (any it doesn't matter, prefer 10.04 LTS since it has 3 years support for it and it's softwares). Just download the ISO image and burn it on a CD/DVD (well you will need another cd drive to do so). If you really have no other optical drive at hand, download unetbootin:
http://unetbootin.sourceforge.net/
then format an USB key or hdd, install unetbootin then make it install any Linux distro on it. Then you reboot your computer with either the USB key/drive plugged in, or CD/DVD in another optical drive (if you can), change boot order in your BIOS to let the corresponding media boot before de HDD.
You'll just need to try ubuntu or whatever Linux distro you got, then in the desktop you will be able to eject it.
