Discussing fastboot configuration changes within the BIOS setup
It shouldn't matter for Ubuntu either way. However, using fastboot on a minimal setup could complicate returning to the BIOS, as the time needed to press a key is reduced. You might be mixing it up with the Windows fast boot feature (Windows Fast Startup). That option should be disabled if you need to access your Windows drive from Linux. Otherwise, it risks corrupting your Windows installation.
You're not using a dual boot setup. Choose minimal for simplicity or auto for convenience.
I mentioned that Ubuntu doesn't matter either way. Choose whatever suits you best. It only influences the POST stage, not the full boot sequence. The overall boot duration equals the time the BIOS needs to POST plus the OS startup. Minimal shortens this by skipping certain checks, doing all checks and taking the longest. The actual Ubuntu boot time stays the same in both scenarios. Minimal could complicate getting back into the BIOS since the key press window is very short. It might also not properly set up unusual hardware. Auto usually runs a bit longer but tries to handle devices wisely. Thorough takes the most time because it initializes everything, including unnecessary parts, and is safest with exotic gear. It should also help you return to the BIOS more easily—just test it, see if minimal changes performance noticeably, and ensure everything functions as intended. It shouldn't cause issues and you can always revert if needed, as long as you can access the BIOS.
