What is USB booting and how does it work?
USB booting is a process where a computer boots up from a USB device instead of its hard drive. This is possible because modern computers have a feature called USB boot option or USB booting, which allows them to recognize and boot from USB devices. When a USB device is plugged in and the computer is restarted, the BIOS (Basic Input/Output System) searches for a bootable device, and if it finds one, it boots from it.
The USB device must be formatted to be bootable, and it must contain a valid operating system or boot loader. The boot process is similar to booting from a hard drive, but instead of reading from the hard drive, the computer reads from the USB device. This allows users to boot from a USB device even if their hard drive is faulty or not recognized by the BIOS.
