I have a Sony Vaio Ultrabook SVT 131 with Pro Duo SD Card slot. I have installed a live Ubuntu on a 2 GB Sony SD Card and plugged it in my Ultrabook. Then I am trying boot my Ultrabook from the SD Card.
First I have accesed the BIOS setting and enabled booting from Media devices also I have choosed to boot from Media devices. Unfortunately I got "No operating system message" when I booted. I am sure that my SD is bootable. I downloaded last Ubuntu ISO then use USB tools to extract and create a live version on my SD Card.
I have also tried to change Boot option from UEFI to the normal legacy but I have got the same.
