Chosen Solution
I have two partitions in my iMac, one with Windows 10 and another with OS X Mountain Lion. I need to run ArtiCad a software that only runs in windows and that is already installed. It was all pre-installed to boot on startup immediately in Windows ambient and now it just doesn’t boot at all. Only a white screen shows up. How can I solve this problem? Kind Regards, José Freire
Boot from an external USB drive with a compatible system installed and run Disk Utilities on the internal drive.
