I own a 2011 Macbook Pro 15" high end with a Samsung 470 256GB SSD. I have downloaded the latest Samsung Magician software (3.0) and ran it in Windows 7 through bootcamp. It said there was a firmware update for my SSD. Into Magician, i created the bootable usb with the firmware update but when i restart the macbook, i press alt and the only options to boot are bootcamp or OSX Lion... How can i boot from the usb to perform the firmware update? Is there any other way to update my Samsung 470 SSD firm? Thanks in advance.
