Hi everyone, I have an issue I could really use your help with. I installed windows 7 on my iMac, but find that I cannot boot back to lion. There is no boot camp function, and one option I clicked on, only windows 7 is shown S an option. Could I have accidentally erased my osx partition? What Options do I have to remedy this? I downloaded lion from the net, and so I don't have an installation disc. Your help is urgently needed. Thanks!
