Here are a few things to try:

  • Make sure secure boot is off, it can't boot otherwise
  • It seems obvious, but try reinstalling ubuntu, try the advanced mode to fiddle around with partitions. Make sure there's a swap partition, root partition and maybe a boot partition (Source)
  • Try using a different program to write ubuntu to your flash drive and make sure to confirm the checksum is the same as the one on the website.

Hopefully this helps (it probably won't)
