I have managed to avoid installation via the optical drive and have been using a USB. After receiving this error (and after formatting right there with what they give me) I go back to my disk utility and erase the partition after changing it to exFAT and go back to the Windows partition to see if it worked but, nothing changed. Can anyone out there tell me what I need to do to fix this? Or how to change the MBR partition table to GPT? Thanks!
