I have want to install Ubuntu on my Udoo x86 advanced plus but since I cannot get into the bios...I seems to me I won't be able to?
Make sure you are holding the ESC key down early enough in the boot process. Hold it down while powering up, if need be. Make sure your keyboard works.
And if you get a black screen, try another monitor (or TV). The UEFI is sometimes not recognizing the display device.
