Hi. Where did the rest of this discussion go? I'm having this exact problem (with what looks like the same or similar BIOS, based on that photograph): my computer won't boot from the correct HD. When the BIOS is set not to use 'legacy', I can't see the individual drives in the boot order (though I can see them in the device list). The boot order just has
ubuntu, Linux Firmware Updater and Windows Boot Manager. When I enable legacy booting, I see both drives, but booting doesn't work.
