Hi, I have a Mac-mini mid-2011 and I just purchased an external hard drive for it. I'm trying to setup the external drive so I can boot both Lion and Mountain Lion. The first step was to format the external drive using Disk Utility. That went fine. I created 2 partitions and formatted them HFS+ journaled. Now what I want to do is to create an image backup of my existing Lion installation and copy it to the external drive. So simple, hold down Command-R while restarting and boot into the recovery utilities. Right? Well, wrong! For whatever reason, this Mac-mini refuses to boot into recovery tools. I am using a Windows keyboard. So I tried the WindowsKey-r = nope. Tried the AltKey-r = nope. Tried the WindowsKey-AltKey-r = nope. So how do I get booted into the utilities on this Mac-mini? .
