Booting from a USB drive can be a lifesaver when you need to install a new operating system, run a live version of an OS, or troubleshoot a computer that won’t boot from its internal drive. However, to do so, you need to enable BIOS to boot from USB. In this article, we’ll take you through the process of enabling BIOS to boot from USB, covering the basics, the steps involved, and some troubleshooting tips.
Understanding BIOS and Boot Order
Before we dive into the process of enabling BIOS to boot from USB, let’s understand what BIOS is and how it works. BIOS (Basic Input/Output System) is the firmware that controls the basic functions of a computer, including the boot process. When you turn on your computer, the BIOS is the first thing that runs, and it’s responsible for initializing the hardware components, detecting the boot device, and loading the operating system.
The boot order is the sequence in which the BIOS searches for a boot device. The typical boot order is:
- Internal hard drive
- CD/DVD drive
- USB drive
- Network
However, this order can be changed in the BIOS settings, allowing you to boot from a USB drive or other device.
Why Enable BIOS to Boot from USB?
There are several reasons why you might want to enable BIOS to boot from USB:
- Installing a new operating system: If you want to install a new operating system on your computer, you’ll need to boot from a USB drive containing the installation media.
