Hi there,

My university asks all Mac users to install Windows on their computer using Boot Camp. The school provided me with a .iso file of Windows 7 Professional but Boot Camp requires that I use a disc.

Is there a way to burn that ISO file onto a DVD so that I can install it using Boot Camp?

I tried using the Disk Utility but it won't allow me to burn the file. It says that it is "not recognized".

What should I do?

Thank you,

Matt

    If the above instructions won't work, then you have a defective iso image.

    be sure the blank disc matches the image size (is big enough).

    This one's SL compliant. http://www.macosxhints.com/article.php?story=20100527035147137 See the first line:

    *hdiutil makehybrid -o ~/Desktop/Diskimage.iso ${diskName} -iso -joliet*

    Hi baltwo:
    an already created iso file should burn properly (with it's original format) "as is". If it was
    joliet, it should still be joliet after burning. However, if you are mastering a new DVD, then the
    command line you posted will be necessary to make a hfs/joliet (pc/mac) version.

    Another option with a previously mastered iso file is to use DU to covert it to a "cdr" format
    before burning. If it won't convert, then the the iso copy is defective. iso is a "template" and
    DU simply copies the template bit by bit to disc.

    converting to .cdr format is probably the most foolproof method, but it is actually an unnecessary
    step, iso's should burn "as is" if the proper steps (put in blank DVD, open iso image with DU, select/highlight iso image in left column and press burn) are executed. An exact copy of the
    original DVD should be created.

    Hi there and thank you for the responses!

    I followed the direction from this site: http://www.macosxhints.com/article.php?story=20060619181010389

    However, when I try to open the ISO using File>Open Disk Image it tells me that it was unable to attach and that it was not recognized.

    Does this mean the school gave me a faulty file?

    Might there be another way to install Windows using boot camp?

    Thanks again,

    Matt

    Thanks for the additional information.

    I think your file is faulty.
    I recently created a windows backup disk. I created the an iso file from the windows install disc, in windows running under parallels Desktop, using IsoBuster.
    http://www.isobuster.com/

    I burned the iso to disk using disk utility and tested the backup copy, and it works flawlessly.
    It is just like the original in every way.

    I suspect whoever created the iso file, did a poor job.

    One other thing though:

    Just because you can't mount a windows .iso cd/dvd file, doesn't mean you can't burn it!
    In fact, the "unable to attach/file not recognized" error message is normal for a PC .iso file.

    After you burn it, your Mac can read the finished DVD (how is that for weird?).

    In other words, Disk Utility won't mount a non-hfs iso file, but it can burn one.
    After it is burned, your Mac can read the finished iso-9660/Joliet CD/DVD.
    Furthermore and forth-whence, a dual (PC/Mac) DVD such as the Snow Leopard install disk,
    (SL DVD has dual hfs/iso-9660 formatting), in a Mac only the hfs (Mac) files are visible. Put
    the SL install DVD in a PC and only the Boot Camp Driver (PC) files are visible. Cute, huh?
