Cool. That what I was wondering. If the boot loader permanently stripped code out of the BIOS permanently, effectively making is un-boottable in other configurations. I was also wondering if all the new boot loaders like Chameleon EFI/UEFI or Clover EFI or UEFI access the EFI to make the machine behave like a hackintosh or if they just spoof the OS directly in some other method? I see in some older Clover boot loaders have an option to mount the EFI partition, but I do not see that in recent Bootloaders in Clover, but I could be looking in the wrong place..? AGAIN, Rehab Man is the xOS X King for his knowledge..
