What is booting from USB, and how does it work?
Booting from USB means using a USB drive as the primary source to boot up a computer, rather than the traditional hard drive or solid-state drive. This is made possible by the computer’s BIOS or UEFI firmware, which allows the system to recognize and prioritize the USB drive as a boot device. When a USB drive is inserted and the computer is restarted, the BIOS detects the USB drive and loads the operating system or boot loader from it, allowing the computer to boot up normally.
The process of booting from USB works by creating a bootable USB drive, which contains the necessary files and drivers to load an operating system or run a live environment. The USB drive is then inserted into the computer, and the BIOS is configured to prioritize the USB drive as the first boot device. When the computer is restarted, the BIOS loads the boot loader from the USB drive, which in turn loads the operating system or runs the live environment, allowing the user to access the computer’s hardware and software resources.
What are the benefits of booting from USB?
Booting from USB offers several benefits, including increased portability, convenience, and flexibility. With a bootable USB drive, users can carry their operating system and applications with them, and boot up any compatible computer without worrying about software compatibility or installation.
