What is Bootloader?
The bootloader is a program that starts whenever a device is powered on to activate the right operating system. It is therefore not only a trait reserved for Android but also one that can find out all devices with an operating, be it a smartphone, a tablet, a PC, etc.

It may occur that a device, a computer, for example, may be equipped with two different operating systems (dual boot). In this case, either one or the other bootloader starts, depending on the user's preference or what has been pre-programmed to happen automatically.

Why Xiaomi or other company locked their device Bootloader?
Manufacturers lock the bootloader of their devices so that only the operating system installed on the device can be used. Not all brand acts in the same way either: some manufacturers release their smartphones with the bootloader already unlocked (to the delight of most computer geeks). Unlocking the bootloader allows you to install unauthorized software, this operation voids the warranty of your device.
