I've been tasked with fixing a Mac Mini that was meant to function as a dual Mac/Windows machine, but somewhere along the road something went horribly wrong. The machine always boots to windows, whether or not the option key is held down. In addition, booting from ANY CD, be it a windows install disc or the Snow Leopard disc, brings up a "grub" prompt with the message "Minimal BASH-like line editing is supported...". I've never seen anything like it. I suspect a problem with the bootloader? Is it possible to restore it without harming the other partitions on the disc? How can I at least get access to booting to CDs? Any help is appreciated!
