    Hi,

    My internal DVD is not working anymore and I want to install Windows.

    I know it is possible to install Windows using an external DVD on a Macbook Air.

    But is it possible on an iMac.

    Since I have problems doing this, I ask the question in this forum ???

    To be specific: my problem is that the screen remains gray, when I select to boot from an external DVD containing a bootable iso of windows 7.

    Not all combinations of external optical drive and Mac work equally.

    There is an entire long thread dedicated to this topic, namely installing Windows without a working internal SuperDrive.

    Your best two options are:

    1) Use VM software to perform the first part of the install, completing it on native hardware
    2) Copy the contents of the ISO to a throwaway internal partition (as if to a USB drive) and boot/install from that.

    Thanks for helping.

    It seems to me that (2) is the most easy solution, although I do not know how to make the partition bootable.

    It's all in the thread I linked to. Basically you follow the same approach that is used to copy the ISO to a USB flash drive, only to a partition.
