Is there a way to make Windows 7 install .iso onto USB drive from OSX?

Solution 1:

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
