Just two days ago, the machine had a Windows 8 partition on it, but it was full of malware slowing it down and hurting it. I backed up all important files and formatted the drive, so to install Windows 10 from a WININSTALL USB drive, I created on a different computer. I've tried as many things as I could think of, or find online, even going as far as to do a full wipe of the entire Hard Drive.
Boot Camp Assistant, when functional, give me the error that "Windows cannot be installed to this disk. The selected disk has a mbr partition table, On EFI system window can only be installed to GPT disks."
Installing on a partition of pure Free Space returns the error "Windows could not update the computer's boot configuration. Installation cannot proceed."
I've done some reading, and it seems this older model isn't EFI compatible. If this is true, what alternatives do I have? If not, what can I do to move things forward. Thank you!
