METHOD OF USING DUAL-BOOTING AND MULTI-BOOTING OF MICROSOFT WINDOWS FAMILY OPERATING SYSTEMS ON EXTERNAL SYSTEM DRIVE

Abstract

Computer’s operating system in generally installed on its internal SSD (HDD). When user boot computer, the BIOS loads the boot loader from the internal SSD and the boot loader boots the installed operating system. A boot loader is a computer program that loads an operating system or some other system software for the computer after completion of the power-on self-tests. A boot loader is loaded into main memory from persistent memory. On modern general purpose computers, the boot up process can take tens of seconds, or even minutes, and typically involves performing a power-on self-test, locating and initializing peripheral devices, and then finding, loading and starting an operating system. Booting is complete when the normal, operative, runtime environment is attained.

Dual-booting is a technique which allows a single physical computer to run two operating systems.

Multi-booting allows to the common configuration of multiple operating systems on computer, and ability to choose which operating system to boot.

I have Implemented method of using dual-booting and multi-booting based on the external SSD system drive.

Key words: system drive, HDD, SSD, operating system, installation files, WIM-file, DISM, Diskpart, BCDboot, Microsoft Windows.
