What is USB booting?
USB booting refers to the process of starting up a computer using a USB flash drive as the primary source of the operating system, rather than the default hard drive. This method is particularly useful for installing new operating systems, troubleshooting existing installations, or running live operating systems without affecting the internal storage. USB booting has gained popularity because it offers a convenient way to carry operating systems and necessary applications in a portable format.
When a computer boots from a USB drive, it reads the bootloader located on the USB device, which then loads the operating system into memory. This capability allows users to perform installations or repairs on machines that may not have an operating system installed or where the existing OS is malfunctioning. USB booting is supported by most modern computers and laptops, provided that the device is configured to prioritize USB devices in the boot order.
How do I create a bootable USB drive?
Creating a bootable USB drive typically involves using specialized software designed to transfer an operating system image (ISO file) to the USB device in a manner that it becomes bootable.
