That is, you put your Windows 7 DVD into some USB DVDRW to install from? I see folk lose a lot of time trying to install from USB sticks.
So, a little background information might be practical.. I have a 2012 Mac Mini, on which I am trying to dualboot Windows 7. I created a bootable USB in the bootcamp utility and started the installation by holding 'alt' and starting from the bootable USB. All installed correctly, until I got to the 'Windows will continue your installation after rebooting' part. After rebooting the mac mini and holding the 'alt' key again to boot into the right partition, it just shows a little flashing white horizontal 'cursor' and doesn't continue to do anything. I left it alone for a while, but it didn't do anything apart from flashing.. So I restarted and tried again by booting to the USB after the reboot part.. That didn't help, as it just gave me the Install now screen.. Anyone any idea what I'm doing wrong?
