What is USB Boot and how does it work?
USB Boot is a feature that allows you to boot your computer from a USB drive, rather than the traditional hard drive or solid-state drive. This feature is useful for installing operating systems, running diagnostic tools, and troubleshooting computer issues. When you enable USB Boot, your computer will look for a bootable USB drive during the startup process and load the operating system or software from the drive.
To use USB Boot, you need a USB drive with a bootable operating system or software installed on it. You can create a bootable USB drive using software such as Rufus or Etcher. Once you have a bootable USB drive, you can insert it into your computer and enable USB Boot in the BIOS settings. Your computer will then boot from the USB drive, allowing you to access the operating system or software on the drive.
Why do I need to enable USB Boot in the BIOS settings?
Enabling USB Boot in the BIOS settings is necessary because the BIOS (Basic Input/Output System) controls the boot process of your computer. The BIOS determines which device to boot from, and in what order. By default, the BIOS is set to boot from the hard drive or solid-state drive, and not from a USB drive. To change this, you need to access the BIOS settings and enable USB Boot.
Enabling USB Boot in the BIOS settings allows you to prioritize the USB drive as the boot device. This means that when you insert a bootable USB drive into your computer, the BIOS will recognize it and boot from it instead of the hard drive or solid-state drive. This is useful for installing operating systems, running diagnostic tools, and troubleshooting computer issues.
How do I access the BIOS settings on my computer?
To access the BIOS settings on your computer, you need to restart your computer and press a specific key during the startup process.
