    Hi all,

    I'm sure this has been answered many times. I tried searching, but I just got lost. Perhaps a sticky may be good?

    I have an internal SSD Evo 850 250GB drive that I want to use for Windows 10. I have a Windows 10 .ISO.

    I have an internal 500GB PCIe SSD that I will be using as Mac OS (which I will be using 90% of the time).

    What is the process of loading Windows 10 on my 250GB drive?

    I understand that there's an EFI method vs a Bios method. Not sure of the differences.

    I currently have an Apple 5770, but I'm sure I'll be moving onto a GTX 680 or better in the future.

    Is there any step-by-step processes that would work best for me? Any shortcomings that I should be aware of?

    • Insert the Windows disc and reboot.
    • Hold ALT/OPTION during bootup.
    • Select "Windows" for BIOS install or "EFI" for EFI install. Personally I did EFI.
    • Direct Windows to install to the appropriate drive. Personally I had already removed all other drives prior to installation, in order to prevent an accident.

    Hmm, so somehow I need to take this windows iso and convert it into a bootable disk in MacOS. Any ideas? Maybe just let Toast do it's thing as an image file....

    In Toast do a "Copy Disc" and "Select from Image File".

    In Windows you can use the free "Media Creation Tool".

    Mango, I have an older version of Toast. (Toast 8 Titanium).

    I did Copy -> Image File, and just dragged over the Windows .ISO.

    Upon booting (option key held down), I only get one image named "WINDOWS". No EFI in sight. I didn't pull anything out of the machine yet, just wanted to test to make sure the EFI image is showing up.

    I'm assuming I should see two things, one that denotes an EFI and the other that denotes a BIOS.

    I didn't proceed because of that. Let me know what you think.

    Also, is there any way I should prep my SSD that I will be using in Disk Utility before beginning?

    Got it working by following a guide to image a USB drive.
