Boot camp insert boot disc and press any key
So I'm trying to install Windows 7 on my 2011 MacBook Pro without a disc. I used Toast Titanium to mount the iso file and that seemed to do the trick. After partitioning the hard disk, boot camp recognized the software and moved forward with the installation, however after rebooting a black screen saying "Insert boot disc and press any key" appeared. Pressing any key does nothing. My only option is to hold option while rebooting and selecting my internal hard drive and running OS X. I can't figure out for the life of me how to reboot with Windows. It just isn't working.
Am I missing a step? Anyone have a solution?
Thanks guys.
