I had OS X Lion and Windows Vista installed on my iMac. I wanted to re-install my Lion and in the process I removed it but could not re-install it since Apple have removed it from Mac Store.
Now my Mac system has only Windows Vista. It boots with Vista only. I have to get back to Mac OS X.
I have a DVD of Snow Leopard. When I insert it and hold C during startup, it ejects the drive again.
I've tried starting into Recovery but CommandR doesn't do anything. It boots into Windows Vista.
I can boot into the Recovery system holding Alt, and I have the option to reinstall Lion. When I click on it, it takes me to next screen with title Install Mac OS X. But I get an alert saying Mac OS 10.7 is not available.
I checked Disk Utility also. There now I have Mac OS X Base System. I tried to check the restore tab but I am not able to do anything there.
