Yes, but Fast Boot is also an option in the BIOS on many machines.
That might be the case on newer laptops, but I’ve rarely seen it before.
Fast boot in BIOS isn’t common on a lot of hardware; it’s more frequent on desktop motherboards from non-OEM manufacturers. Fast boot in BIOS skips some functions to go directly to POST, meaning you can’t easily access the BIOS; you’d need to restart to BIOS from Windows or Linux using UEFI. Windows fast boot is similar to the ‘deep sleep’ function from older Windows versions, writing RAM to storage HDD/SSD before shutting down, which can cause issues. It’s less useful on SSDs.

I don’t have an issue with Fast Boot itself, but I want a clean start each time I turn on my PC—not from a deep sleep, which isn’t really a shutdown.

With an SSD, the time saved is minimal, but imagine booting up in less than 5 seconds… that would be incredible!

2.5 seconds, I have the M4 MacBook Pro
Is it really a boot or a wake from sleep? On systems like the one shown in the video, the POST alone takes about 5 seconds. Even if Windows or Linux boots in 1ms, it will still take 5 seconds to be fully up and running. Windows only starts to boot when the ACER logo with the loading white circle shows. Before the ‘white circle,’ the system waits for a prompt to go to BIOS, which takes about 2 seconds. You can sometimes disable this in the BIOS.

A 5-second POST is pretty long for a laptop these days. Also, we don’t know if the original poster has fast boot enabled or not; if yes, then it’s not really a boot either.
