Q: Installing Windows 7 on Mac Pro OSX 10.8.4

As the title suggests im trying to install Windows 7 on my Mac Pro.

There are a few issues im coming across whilst trying to complete this. The main being that Boot Camp doesnt recognise the Windows disc to install from. After further reading i saw that you could essentially mount an ISO to a USB via Boot Camp. I did this successfully and then when i tried to click on 'Install' after deciding the parition sizes i just get the message 'The installer disc could not be found' - so to me its not attempting to locate the USB to try and install from. I could be way out on this and it be that you cant actually install from a USB.

So basically if anybody could provide some advice on how to install Windows 7 from a USB on my Mac Pro via Boot Camp

Cheers
