First off, theres a million ways to eject the dvd drive if its stuck, so go google if this article isnt enough for you.
ive been all the way around from pressing multiple keys at boot up, clicking the left mouse button, etc etc etc.
and since im using Windows 7 (go hate on me mac fanboys) i can´t use various os x ways.
anyway, when trying to eject your cd/dvd from windows, it pops up with a message i forgot all about (some weird error) and its just impossible to eject it.
