I downloaded a copy of windows 7 and now I am trying to use boot camp to install it on my mac. With boot camp, it says I need the ISO file on a flash drive in order to create a win 7 install disk. I currently do not have a flash drive. I was trying to burn the ISO to a DVD using disk utility but I keep getting an error: "unable to burn [name of ISO file] (internal error occurred)". I am using a blank DVD+R disk. Any help would be appreciated!
