eMac G4 Recovery Mode with Windows Keyboard I recently acquired an eMac G4, but I did not get an Apple keyboard with it. I need to restore it to factory settings, but cannot access recovery mode with my Windows keyboard. I've tried Alt+R, Ctrl+R, and Start+R, but nothing. Is there any way to access recovery mode with a windows keyboard?
OS X Recovery was introduced with OS X Lion. At best, your eMac supports 10.5.8 Leopard. If you want to install from scratch, you'll need either the original install disks or a system installation disk.

You can bring another bootable OS X drive that runs a supported OS for that hardware and get to things like terminal / Disk Utility as well but this hardware pre-dates recovery on the firmware / OS level.
