    The USB Boot Disk option in Bootcamp assistant to my understanding, is only functional on the Retina MacBook Pros and the MacBook Airs that were built after 2010. If you don't own those models making a USB boot for WIndows 7 is not supported.

    If you get the option in the Boot Camp program is should be supported.

     

    To make a bootable USB drive with Windows on it there are a few things that should be checked and OK. Do you get an error? If so, what does it say?

     

    At what point does Boot Camp say that it's not possible to make the bootable USB drive?

    I have had the exact same problem.  I get the error that it cannot make a copy of the windows software.  the process stops at that point.  You have to quick the Boot Camp application.

    I forgot to add that I have a Macbook Retina Pro with Mountain Lion OS 10.8.2.  I created an iso file of the Windows 7 Ultimate before that on my other Windows Laptop.

    Is your usb drive formatted with the correct partition scheme? MBR?

    Thanks for the tip Willemisshn.  I will check the partition scheme and set it to MBR if you think it will work.

     

    I did manage to get it to copy across the WIndows software from an ISO file on another USB stick.  I then used that to create a Windows install on the formatted USB drive.  It worked the second time around and not the first time for some reason.

     

    I redid the steps as suggested in the Boot camp guide and it installed the software a second time around.  I then did the second step to install the Windows Support drivers and then did the partition.  When I rebooted it, I then added the USB drive and it installed Windows 7 Ultimate fine after that.  I then ran the WIndows support setup.exe and then updated the system after that.  It is working fine now and I am very impressed seeing Windows 7 on my Macbook Pro.  I can now use ArcGIS which needs all the speed and power that I can muster from my Macbook Pro.

     

    Thanks for your suggestion.

    Make sure you download the instructions to load windows7 using bootcamp.  I found that if you repeat the steps in the bootcamp assistant, you will find that it will work.

     

    First have you managed to set up a USB install disc based on step 1.  Second put the windows support software onto your hard drive or another USB stick.  You need to copy the windows support software across to the USB install disc you made in step 1.  Make sure you create a separate folder for the windows support folder.

     

    Then you can proceed to step 3 to create a partition for Windows.  I set it to 50% which created a 230 GB partition for Windows and 230GB partition for my Mac OS.  You need to create a partition at least 100 GB for WIndows to have enough space for the software.  You may want to increase this to 150GB to create enough storage for data and images.

     

    I found that you had to make sure that you were successful in each of the steps to create a windows partition before moving to the next step.  What mac notebook are you using?

    I just installed W7 2 more times.

     

    And about the partition at least 100 GB isnt true. Its the matter for what you will use it.

    100G is a sensible size, but if you use less you can post back here in order to find out how to enlarge it later.
