So I'm trying to update my SSD Firmware on a kingston SHSS37A240G. I've downloaded the ISO file for the update, I've used rufus to create a bootable USB, but when I boot from the USB in my BIOS and select "live - boot the live system" it takes me to a grey Screen with a flashing underscore in the top left hand corner.

Did I miss something?
