Minimal BASH-like line editing is supported

[chinatefl]

I use Rufus to make dcore-focal64.iso into U disk boot disk. Plug in a z3850 computer. UEFI set U disk to start. Results it failed to start successfully. The error prompt is similar to: minimal bash like line editing is supported..
What's wrong with me?
