I have decided to start to use some of my old hardware kicking around the house for installing Linux (in this case Ubuntu). Everything appears to be fine with regards creating a USB flash drive, however I am having issues with the BIOS as there never appears to be the option to boot from the USB drive. 

The machine a Precision M50 (so a far few years old), has the latest A12 Bios upgrade, however there never appears to be an option to boot from a USB drive. 

Is there a way to add a USB drive to the list of bootable devices ? If yes, how ?
