So, my macbbok (unibody alu), has a broken mac os partition and a working partition. But I can't change to witch partition I boot...

I tried restoring the mac partition with the mac os installer. I also changed my boot partition as the windows one because I had some work to get done. But then I got this weird problem, I couldn't boot from the CD or change witch drive boots. The EFI didn't seem to be responsive to anything so I tried reseting the P and NVram and now it just tries boot in the broken mac partition. (I can also get the verbose)

Essentially, when I press option while booting, nothing happens. I can't boot by pressing C to CD. A ubuntu live CD is stuck in it, pressing the trackpad while booting doesn't seem to eject it either. Also, when I was able to start in windows, using the bootcamp assistant, I couldn't get it to restart into the broken partition or the mac os DVD.

Ideas ?

UPDATE : I tried plugging an external mouse and was able to eject my CD, I think it's booting up to the install DVD right now. (grey apple and spinny thing, could also be my broken partition)

UPDATE 2 : Still can't boot from the DVD drive, back to square one essentially, trying with an external apple keyboard *** THAT didn't work either, I'm out of ideas...
