Booting process of Android devices. The booting process of Android devices starts at the power-on of the SoC (system on a chip) and ends at the visibility of the home screen, or special modes like recovery and fastboot. [a] The boot process of devices that run Android is influenced by the firmware design of the SoC manufacturers.
Bootloader unlocking is the process of disabling the bootloader security that makes secure boot possible. It can make advanced customizations possible, such as installing custom firmware. On smartphones, this can be a custom Android distribution or another mobile operating system. Some bootloaders are not locked at all and some are locked, but ...

Boot services are available only while the firmware owns the platform (i.e., before the ExitBootServices() call), and they include text and graphical consoles on various devices, and bus, block and file services. Runtime services are still accessible while the operating system is running; they include services such as date, time and NVRAM access.
In Windows NT, the booting process is initiated by NTLDR in versions before Vista and the Windows Boot Manager in Vista and later. [4] The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory. Once all the boot and system drivers have been loaded, the ...
Booting. A flow diagram of a computer booting. In computing, booting is the process of starting a computer as initiated via hardware such as a button on the computer or by a software command. After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory ...
Windows Boot Manager does so by reading Boot Configuration Data (BCD), a complex firmware-independent database for boot-time configuration data. Its predecessor, NTLDR, does so by reading the simpler boot.ini. If the boot.ini file is missing, the boot loader will attempt to locate information from the standard installation directory.
