error: symbol 'grub_register_command_lockdown' not found.

    How did you make your Ubuntu pendrive? What tool did you use? Do you want to install Ubuntu to the pendrive or to the hard drive? there may be many reasons that a bootable USB is not booting, see: askubuntu.com/a/1190765/43926 Apr 25 at 11:26

    @David how do you expect the OP to post text, is he suppose to retype it? In this case how is retyping the screen shot and posting it as text help answer the question? Apr 25 at 11:34

    @C.S.Cameron : Pictures of text cannot be found by searching. Consequently, unless the text is typed, no future visitor facing the same message can find this Question by searching. Apr 25 at 19:51

    @Eric Towers Why do you say it is resolved? There are some good reasons listed on that page for posting photos. I do not see it as a rule in Ask Ubuntu Help. Some photos of boot screens cover a whole page of writing. These would not be practical for the OP to transcribe, nor necessarily helpful. Apr 26 at 14:19

If you used Rufus to create the installation USB stick, then you’ll need to download version 3.14 (or newer) and recreate the media. Otherwise, there is a security patch that will need to be installed.

This comes from the developer of Rufus who recently provided a bit of detail about why the issue is happening 😕
