    The disk is 100% legit in every way, not trying to steal this... but I also don't want to buy windows again (download the iso from microsoft after paying $150).

    Okay, so I got into the bootcamp setup assistant and it says I need a USB memory stick (easy enough, have an 8gb one right here) and a Windows 7 iso file.

    Okay, so I put my windows 7 disk in my iMac, go to disk utility, new, image from CD/DVD, select the dvd, and it makes a DMG. Rename it with .iso, try it, nothing boot camp says it's no good.

    Go back, new image from CD/DVD, this time make it a .cdr file. Export, rename as .iso... boot camp setup assistant still rejects it.

    How can I make a .iso that's acceptable to the Boot camp setup assistant from my windows 7 DVD? :confused:



    Oh, and fwiw, the error the bootcamp setup assistant is giving me is:

    Sorry I don't recall exactly what I did but it seems like I made my iso on a windows system ... but however you do it I don't think you should create "something.suffix" and then rename it later to "something.iso" ... that's probably what is messing you up?

    Seems like other threads in here have some step by step instruction links if I were you I would start looking around and doing some searching here.

    Agreed completely. Did it because I read about it on a thread on here.

    Also tried this:

    ... with no success :(


    I think I've figured out my issue. The version of windows I have a license for is 64 bit enterprise... which Boot Camp doesn't support :(

    Update: for the first time in my life, I'm going to see a Genius about a mac issue.

    Will be interesting to see how it goes.

    Been using macs for 20 years now, I never gone anywhere for outside help before. Feels Dirty :rolleyes:

    Final update:
    Geniuses weren't able to figure it out. But, I finally got it going on my own.

    Here's what I did that worked for me...
    1) download windows iso directly from microsoft
    2) use the microsoft made, windows only software that makes a bootable USB stick from a windows 7 iso. Use it to make a bootable USB stick on one flash drive.
    3) use boot camp setup assistant but DON'T check "create windows 7 installer" option (the top one). Do have it download the drivers, and write them onto a second flash drive (yes, you need two)
    4) partition the drives using bootcamp setup assistant and restart
    5) install windows. Once install finishes, run the driver install from the second flash drive.
    6) Optional, but with an air I'd do it (I only allocated 20gb for my windows partition)-- trim the fat off windows 7. I brought it from 14 gb installed, fresh, down to 8gb. Might poke at it a bit more, but that's already a huge improvement.
