Command-R not working on Start-up
I need to do a clean install of Lion on my iMac and I'm using the Wireless Bluetooth Keyboard. But on Start-up using the Command-R function, it still takes me to the Login screen. I've tried it with another bluetooth keyboard, but still no solution. Is there any way to fix this? Or do I need to go out and purchase a Wired Keyboard?
