there may be a way I can check tonight normally I burn Plop to a cd boot the cd and the plop menu will offer up usb options to install I also suspect your bios can boot to usb directly but usb options will only be shown if the usb is plugged in and and sometimes shows up as a harddrive not a usb also check as usb devices are often disabled by bios as a boot option by default sometimes are well hidden in menus and hard to find On Wed, Apr 10, 2019 at 2:33 PM Jim wrote: > My system normally boots from /dev/sdd1.
