GrimeFigher start problem

Computer - IMac
bootcamp
OS - Windows 7
While starting GrimeFigher - computer reboots, than shows black screen with text “GNU GRUB” and so on - and command line - with blinking cursor.
What’s the problem? Is there some command I must write in the command line?
thanks.

Hi GhostBuddy,

GrimeFighter is not supported on Mac. Please open a support ticket at the link below and ask for a refund. The issue is that booting into Linux on a Mac, even with Windows OS is very complicated and is not supported.
