Having issues with the installation. 
  
I bought the The EOSHD 5D Mark III Raw Shooter’s Guide and I am following the instructions.. 
  
When I complete step 5 on page 27,  I get the "BootDiskEnable :-)" message.   But when I hit the trashcan button after doing that nothing happens at all. 
  
I took out the SD card after that to view the contents and there is now a "ROM" file on the card as well.. 
  
also... 
  
When I attempt to make a bootable SD Card,  ML does not boot to the Card,  firmware goes back to its original v1.1.3 and when I try to run the ML install,  it says no update file exists. 
  
Can anyone tell me what I am doing wrong?   I am following the instructions to the letter,  and this process is not working for me 
  
Regards,
