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?
So after trying all these solutions, it still didn't work. I went out and bought a Wired Keyboard from Apple and did Command-R. And to my surprise, it still didn't work! I contacted Apple Support and they finally told me it was because I didn't have the Lion Recovery partition when I installed Lion. I finally just put in the OS disc that came with my iMac, booted from it, and I was able to access Disk Utility and erase my Macintosh HD. Reinstalled Snow Leopard, then installed Lion. Took a long process but clean install was successful!
