I see that in your BIOS that secure boot is enable, you should have it on disable - it can mess withyour Linux system.
Yes
Secure boot is disabled
And Legacy boot is enabled
Welcome to the Forum!
When You press Enter and then use the Arrow Keys to move it up and down, does that works?
When You have Legacy Boot, how do you have created Your bootable USB Stick? Did You used Rufus? With that You can choose between GPT and MBR Sheme. For Legacy should theMBR sheem be a better Choice.

In Legacy Mode MBR should be a better Option. Maybe You should try it again with MBR chosen.
Thanks
