no bootable device when installing windows on mac

I had to eventually remove the USB and reset PRAM to get it to boot into osx again I tried hitting keys with he USB in but nothing happened. I force restarted and the next time it turned on it got stuck on the grey logo for a bit but then proceeded to go to a black screen that said ' No bootable device - please insert a bootable device and hit any key'.

When it came back up it was stuck on a grey apple logo screen forever (I waited 15 minutes to ensure it wasn't just 'thinking'). I told boot camp how much space to partition windows on and hit install. I wanted to install windows 7 on the hard disk with boot camp with a USB and ISO image.Īfter searching I found that I need to modify my to allow my boot camp to create a bootable USB (since normally it doesn't have the option to create the USB for my model since it came with a disk drive).Īfter doing so and seemingly having a fine (but long) install process onto the USB.

So I have a 2010 15' macbook pro (MBP6,1) and I replaced the optical drive with a hard disk.
