Hi,
Sorry about the frustration you are experiencing. The issue here is most likely caused by EFI, which is a replacement of BIOS. In some cases EFI won't allow the PC to successfully boot into Linux, which is needed to run GrimeFigther.
Long story short, GrimeFighter unfortunately won't work on your PC. Please open a support ticket and request a refund. It can take up to 7 days to issue the refund.
Regards,
David
