changing fastboot settings in BIOS question

[HiMrRes23948]

Before i'm going to install Ubuntu 24.04 on my main PC, please i would like to know do i need to set to minimal or auto?

Shouldn't matter to Ubuntu either way. But fastboot on minimal might make it harder to get back into the BIOS, because the timespan to press a key to do so is much shorter.

 

Maybe you're confusing it with the fastboot ("Windows Fast Startup") option in Windows (in case you're dual booting). That one should be off, if you want to access the Windows disk from Linux. Otherwise it can mess up your Windows install.

I'm not doing dual boot. Should I set to minimal or auto??

Yes, use auto.

Do i need to leave it at thorough setting??

As I said, Ubuntu doesn't care either way. Use whichever you prefer.

 

It only affect's the POST process, not Ubuntu's boot process. The total boot time is the sum of time it takes the BIOS to POST and the OS to boot. Minimal reduces time for POST to the absolute minimum by skipping checks, thorough performs all checks and takes the longest. The boot time of Ubuntu itself is identical in both cases.

 

Minimal might make it harder to get back into the BIOS, because the time window for you to press a key to do so is, well, minimal. It could also potentially fail to initialize more exotic hardware. Auto likely takes a bit longer, and should hopefully be clever about the devices it initializes. Thorough will take the longest time to boot by initializing absolutely everything (whether necessary or not), but is the safest option if you have exotic hardware. It should also make it easier to get back into the BIOS.

 

Just try it, see if minimal makes a noticeable difference and stuff works as expected. It shouldn't break anything and you can always switch back, provided you can get back into the BIOS (should be able to force boot to BIOS with "sudo systemctl reboot --firmware")

I'm going to keep it thorough enabled settings in BIOS
