A few days ago, the hard drive gave up the ghost. No problem, I said to myself. I've been backed up with time machine this whole time. Apple is so rad! So I took my iMac to a shop and ha they guy replace my hard drive with a blank one. Then I used the lion thumb drive (I was running lion) to attempt to boot and restore. Fail. Circle-slash. So I used my old Leopard DVD. It told me, "You can't install Mac OS X on this computer, but you can restore.". Okay, fine with me! It restored from time machine... A restore from 2009. Leopard. So I tried the lion install on the thumb drive. "You can't install Lion on this computer.". Maybe that's because I don't have snow leopard. Okay, so I put my install DVD back in. "You can't install Snow Leopard on this computer.". Okay, I think I get it. I did something Apple didn't like. What did I do wrong? And, more importantly, how can I restore back to my old system being held hostage on my external backup drive?
