Windows 10 Bootcamp installation problems on 2012 Mid (non-Retina)MBP

[amadaras]

Hi,
I'm having problems with installing Windows 10 on my Macbook. I'm trying to do it from USB flashdrive. The laptop has a 500GB HDD and a 250GB SSD instead of Superdrive. There's OS10.13 on it, and that's the drive I'm trying to place the Windows installation on.
So I make a Bootcamp partition, make the installflash, reboot. There're three boot options: Macintosh HD, Windows, and EFI boot. When I try to boot 'Windows' up, only white screen appears, until I force-reboot the computer. Now, I try 'EFI boot'. Windows installer loads, I chose language, accept EULA, and I have to chose a partition to install. There's our nice, Bootcamp-created partition, I format it. We're all fine till this. Now the installer says something like 'on EFI systems Windows can only be installed on GPT disks'. No problem -I said- back to MacOS, with gdisk I change hybrid MBR back to GPT. Now I go back to the installer, and look, this problem is resolved. But there's another, and I can't get trough this: 'We couldn't create a new partition or locate an existing one'. I've tried to install windows on the HDD as well, but I got the same result. I don't know what else I could do. So, thanks for any help.
Regards,
amadaras

You have the same model MacBook as me but I have the super drive as I need it with plenty of DVD's. I am also thinking about installing Windows 10.

Apple put a limitation in their firmware that MacBooks that comes with optical drives must install Windows from the optical drive. Apple obviously didn't want you to remove it.

See this thread for a few possible workarounds.

Thats good because I have not removed mine. I need it and am glad it shipped with one. Its a shame Apple does not sell computers that ship with DVD drives anymore.
