I wanted to check out my new iMac first and missed the chance to use setup assistant option. I wanted to reformat my drive and re-install Mountain Lion but I don't see recovery partition either by pressing command + R or by pressing alt/option during the boot. I also tried to use a bootable USB stick of Mountain Lion created on my old iMac. The new iMac will see it, but when I select it during the boot, I get circle with line through it and I can't run it. How can I get it done? How do I access the recovery? Why is it gone? Is it just me, or does anyone else noticed that problem? Thanks!
