I'm attempting to make my USB a bootable windows 7 installation. I have the Windows 7 installation ISO image and related files. When I attempt to format my USB with the files, I receive the error: Boot Camp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation.
My ultimate goal is to make the USB bootable with a new Windows 7 install from within my mac, and then booting my old Windows Vista computer with the fresh install.
How might I get this to work?

Try these steps.
If the item is grayed out, then you must unmount the flash drive. You can do this from the Disk Utility application, but sometimes this fails to work. If you use the Terminal application, you can enter the command
diskutil list
before and after inserting the flash drive in the USB port. The added disk is the one that must be unmounted. Here, I will assume this isdisk1
. The command to unmount the flash drive would then be as shown below.Click on the image of a USB flash drive on the bottom of the virtual machine window. Select the flash drive. If it is still grayed out, then you must repeat step 4.
