USB Booting
USB booting is a process that allows a computer to start up and load an operating system or utility from a USB flash drive or external storage device, rather than from the internal hard drive. It involves creating a bootable USB drive with an OS installer, live environment, or diagnostic tool, and configuring the computer's BIOS/UEFI to prioritize USB devices during the boot sequence. This technique is commonly used for system installation, recovery, troubleshooting, or running portable operating systems.
Developers should learn USB booting for tasks like installing or testing new operating systems (e.g., Linux distributions, Windows), performing system repairs without accessing the internal drive, or creating portable development environments. It's essential for IT support, system administration, and software testing scenarios where direct hardware access or isolated environments are needed, such as malware analysis, data recovery, or benchmarking on bare metal.
