    Hi everyone
    I was trying to install windows 7 using the bootcamp assistant and I've totally messed up. I got to the part where windows was loading set up files then come to the section where it requires you to select which partition to install windows to, however I chose the wrong one and deleted the iMac OS and now my mac is useless saying 'No Bootable Device'

    This is a new iMac with no startup disk or operating system to boot from, can someone help?

    In that case, shut down your Mac first.

    Press the power button and hold down Cmd+R immediately during the startup chime. You'll be put into Internet Recovery mode, where you will be guided and directed to redownload OS X over the internet.

    After that, it will guide you to reinstall OS X.
