    Good afternoon,

    I've bought a new iMac 27" spec:

    3.4GHz Quad-core Intel Core i5, Turbo Boost up to 3.8GHz

    8GB 1600MHz DDR3 SDRAM - 2X4GB

    1TB Serial ATA Drive @ 7200 rpm

    NVIDIA GeForce GTX 775M 2GB GDDR5

    I've been trying to install Windows 7 using an ISO image and Boot Camp Assistant but when I go through the process using an external drive it loads the image on to the drive and then creates a partition on the Imac internal drive after this the computer restarts and then I get the following message:

    No bootable device -- insert boot disk and press any key

    Can anyone help me and advise where I may be going wrong?


    Best Regards

    NWR

    I had the same problem with my 27" iMac, go back in to bootcamp assistant and delete the partition you have created and start over, it should work.

    I've done it twice and still the same result.

    Don't know why it's doing it.
