Hello everyone. I took a fall with my MacBook in my backpack and managed to break the SuperDrive. It does not work anymore and consistently emits a noise upon startup. I decided to disable the SuperDrive all together and followed a guide I found on google which involved deleting IODVDStorageFamily.kext from its original location and keeping the copy elsewhere. Well now I can't turn on my computer and it won't get past the apple screen in startup before giving me a "cancel" symbol. I can't boot from cd because the SuperDrive is wrecked. What else can I do? Thanks so much. Edit- holding shift didn't get me into safe mode I assume since I get the de cancel sign. Also, I have the White MacBook pre-unibody design.
