A Bootloader is a code that runs when we turn on our device. This code initializes some hardware and then loads the kernel and ramdisk, and gets the boot process going. So this process is known as bootloader. The same concept applies to all the technical stuff such as laptops, PC, Smartphones, and any such device. Every Android OEM manufacturers lock the bootloader even though it is an Open Source. So if you want to try any CUSTOM ROM, it is impossible to load the CUSTOM ROM without the Unlock Bootloader.
