Now I am having trouble because this questionnaire keeps asking for more detail and refusing to accept the question even though I have given all of the information I have. I have tried choosing various files to boot from but none of them worked. I have tried: I have read every article I could find and this one was the most detailed but even it didn't tell me this one detail about the proper choice of files for the Boot Selection. I didn't have enough experience to know which file to chose from the USB flash drive LinuxMint installation. The Dell Boot sequence, at least for my 4 year old XPS 13, is more complicated than I have had with other laptops.
Any advice you can give (also for when I want to actually do the install in order to replace Dell's Win8.1 OS with the LinuxMint on the internal SSD) will be greatly appreciated. Sorry to make such a long story out of such an easy question. Please tell me which file to chose for the Boot Option. If I chose the linuxmint-19-cinnamon folder I can chose from "casper-rw", "linuxmint-19-cinnamon-64bit-v2.ISO". There are many files in the main multiboot directory (such as syslinux.cfg) and also other folders (menu, ISOS, and linuxmint-19-cinnamon). Clicking on that multiboot directory, I must chose which file to boot from. I open the EFI Boot Selection and the USB drive lists "multiboot" which is what YUMI created. Then I must give the file name for the boot. Under this option I first give my option the name "USB Drive". Now that Apple has released macOS Monterey to the world there’s a good chance that you might wind up needing to install it on your device afresh.

Finally I went to the Boot Sequence (which now has only "Windows Boot Manager" and the "UEFI: Samsung SSD") and am trying to "Add Boot Option". Here’s how to create macOS Monterey bootable USB flash drive installer, complete with step by step instructions. Check out two main ways of installing Windows on Mac: Boot Camp and virtualization. Then under System Config I checked that "Enable Boot Support" and "Enable External USB Port" were both checked. Next I made sure that "Secure Boot" was Disabled. There I have made sure that POST Fastboot is set to "Thorough". In order to set the boot sequence, I press F2 during the startup and get into the BIOS setup. The computer is a Dell (I think this was the first XPS 13, about 4 years old). I want to boot from the USB to try it live before installing it on my old computer.
I have a San Disk 16GB USB flash drive which I have installed a Mint ISO using YUMI.
Making the correct file choice in EFI Boot Selection?
