    "hdiutil: Invalid El Torito options. Ignoring". And makes the ISO, but no system recognized on boot.


    You probably forgot to run this command before running the one you pasted

    cd ~/Desktop/Windows7

    2nd confirmation for this working on my late 2006 iMac ( IMac6,1 )

    I am installing the Elementary OS and had tried the two methods of creating a bootable usb before trying the bootable dvd.

    I used a wireless apple keyboard to hit OPTION. Then I did held 1 on my hardwired keyboard and carefully watched the blacked screens to jam on the ENTER button any time it changed.

    iMac 4,1 CD (32bit) updated to C2D with 5,1 ROM trying to load Win7 Ultimate 64bit. Got the Select CD-ROM Boot Type message and inoperative keyboard. Following sequence worked for me

    - boot and hold down option key, insert Win7 install disc
    - hold down 1 and boot Win7 install disc
    - keep tapping return key. Windows started loading within a few seconds
