I copied my windows 7 cd to a ISO and trying to source the image onto my USB drive from OSX. So far it doesn't seem like it's possible with disk utility. Is there something else I can do to make this work?

Of course, the command line is always there to help.

  • Insert the USB flash drive and run the command diskutil list to find out the disk name, we'll use /dev/disk1 as an example.

  • Now unmount the disk using diskutil unmountDisk /dev/disk1

  • Now we are ready to copy the ISO to the device:

dd if=/path/to/Win7.iso of=/dev/disk1 bs=8192
