I have a MacBook Pro with Retina Display that I'm trying to get Windows 7 installed on via Bootcamp. I put my Windows disk in to my old MBP and created a .cdr of the disk, change the extension to a .iso and then used the Bootcamp Assistant on my new MBPwRD to create a USB installer of Windows. That goes fine and dandy, but when I finally get to the installation part, Windows craps out at the "expanding" stage and says some files are corrupt or missing. I've managed to get my hands on some other ISOs of Windows 7 to see if maybe it was just mine but no, it happens every time. What am I doing wrong and how can I fix this, please help! Also, my copy of Windows 7 is legal and legit, just in case anyone thinks i'm playing with pirates, arrrrr.
