Okay, so I'm in a bit of a pickle. I tried to partition my HD this evening, only to realise that it was corrupt. Therefore, I need to repair it. To do this, I need to insert my SL disc and run disk utility from there. However, I tried to insert my SL disc and my superdrive is dead. It just spits out any CD after around 15 seconds. So, I can't partition because I can't repair my HD, and if I bought a new HD, I couldn't install SL on it because my superdrive is broken. I do have a Time Machine of my whole system though (can an OS be installed via Time Machine? I've never tried/known). As a last resort, I've considered installing Lion as my primary OS and shunning SL forever (muhahaha ) however I really don't want to do this. Does anyone out there have any ideas on what I can/should do? And as I mentioned above, if I do buy a new HD, can I reinstate SL via my Time Machine external, partition that and then install Lion on it? Thank you very much!
