ok, so stupid me tried to create a linux partition and install the new version f ubuntu just to test it, for some reason it didnt install right. after the failed installation i couldnt boot osx, but then after running "startup disk" from the mac installation disk i was able to start os x and was thankful my stuff wasnt deleted. anyway, now i have these 3 extra partitions, 1 of them i made and the other 2 the linux installation made. i cant get rid of those partitions! when i boot disk utility it says removing volume but it just doesnt do it and stays at that message. what can i possible do to get rid of these unwanted partition that are taking up 15GB?
