Actually, it's not corrupt. I discovered the problem. Apparently grub will not install to the MBR of an EFI system. I discovered this purely by accident as I found this information absolutely nowhere. It will however install to the Windows EFI partition. So I solved my own problem. Someone might want to update the installer so that if it is running in EFI, it should automatically choose the existing EFI partition to install to as default instead of the MBR of the HDD (which will always fail).
