Question Query Regarding Boot

[d4rkErr0R]

As far as I know, there are two types of boot in a computer:

1. Pre-boot
   This typically starts from the moment you press the power button.
2. Post-boot
   This begins when you select the distribution in the bootloader, or is it better to call it distro boot?

Is "post-boot" the correct term, or should it be referred to as "distro boot"?


Also, when systemd or the GRUB bootloader takes a few seconds to initialize the OS, is that considered pre-boot or post-boot?


And when I see the distribution displaying boot logs, is that when post-boot or distro boot starts?

Why the question?

Think of it this way, "pre-boot" is the part where the BIOS initializes the hardware. "Post-boot" is the part when the OS takes over. GRUB would be in the "post-boot" stage.
