In today’s digital age, having a bootable USB drive can be a lifesaver, especially when you need to install a new operating system, recover data, or troubleshoot a malfunctioning computer. However, creating a bootable USB drive can be a daunting task, especially for those who are new to the world of computer technology. In this article, we will take you through the step-by-step process of how to boot from USB, including the necessary tools, software, and precautions to take.
Understanding the Basics of Booting from USB
Before we dive into the process of creating a bootable USB drive, it’s essential to understand the basics of booting from USB. Booting from USB refers to the process of loading an operating system or a bootable program from a USB drive instead of the traditional hard drive. This process is made possible by the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) settings on your computer.
BIOS vs. UEFI: What’s the Difference?
BIOS and UEFI are two types of firmware that control the boot process on your computer. BIOS is an older technology that has been around since the 1980s, while UEFI is a newer technology that has been widely adopted in recent years. The main difference between BIOS and UEFI is the way they handle booting from USB.
BIOS uses a traditional boot process, where the computer looks for a bootable device in a specific order, such as the hard drive, CD/DVD drive, and USB drive. UEFI, on the other hand, uses a more modern boot process, where the computer can boot from a USB drive directly, without the need for a traditional boot loader.
Creating a Bootable USB Drive
Creating a bootable USB drive is a relatively straightforward process that requires a few tools and software. Here’s a step-by-step guide to creating a bootable USB drive:
Tools and Software Needed
- A USB drive with at least 4GB of free space

- Click on the “Create” or “Burn” button to start the process
The process of creating a bootable USB drive can take several minutes, depending on the size of the ISO file and the speed of your computer.
Booting from USB
Once you have created the bootable USB drive, you can boot from it by following these steps:
Step 1: Insert the USB Drive
Insert the USB drive into your computer and restart it.
Step 2: Enter the BIOS or UEFI Settings
As the computer boots up, press the key to enter the BIOS or UEFI settings. The key to enter the BIOS or UEFI settings varies depending on the computer manufacturer. Common keys include F2, F12, and Del.
Step 3: Set the USB Drive as the Boot Device
Once you are in the BIOS or UEFI settings, set the USB drive as the boot device. You can do this by selecting the USB drive as the first boot device or by enabling the USB boot option.
Step 4: Save the Changes and Exit
Save the changes and exit the BIOS or UEFI settings. The computer will now boot from the USB drive.
Troubleshooting Common Issues
Booting from USB can be a straightforward process, but sometimes you may encounter issues. Here are some common issues and their solutions:
Issue 1: The Computer Does Not Recognize the USB Drive
If the computer does not recognize the USB drive, try the following:
- Check if the USB drive is properly inserted
- Check if the USB drive is set as the boot device in the BIOS or UEFI settings
- Try using a different USB port
Issue 2: The Computer Boots from the Hard Drive Instead of the USB Drive
If the computer boots from the hard drive instead of the USB drive, try the following:
- Check if the USB drive is set as the first boot device in the BIOS or UEFI settings
- Check if the USB boot option is enabled in the BIOS or UEFI settings
- Try disabling the hard drive in the BIOS or UEFI settings
