So I am trying to figure out how exactly to install the iso of my Windows XP without having an optical drive on my late 2012 MBP. I was following an online guide and formatted the partition to NTFS (windows) but cannot boot from disc from the start up since I have no optical drive. Is there a way to create a bootable USB drive image to try and install from that? How can I go about installing Windows XP on my separate partition without the use of an optical drive?
