How To Boot Flash Drive


Booting from a flash drive, also known as a USB drive or thumb drive, is a common practice when you want to run or install an operating system or other software. Here are the general steps to boot from a flash drive:

  1. Prepare the Flash Drive:
    • Insert the USB flash drive into an available USB port on your computer.
  2. Backup Data (if needed):
    • Ensure that there is no critical data on the flash drive or back up any important data to another location. The process will involve formatting the drive, which will erase its contents.
  3. Obtain the Bootable Image:
    • You’ll need a bootable image on the flash drive. This could be an operating system installation image (e.g., Windows, Linux), a live environment (e.g., Ubuntu Live, Hirens BootCD), or a diagnostic tool (e.g., MemTest86). Download the image from the official source and make sure it’s in a format that can be used for booting, such as an ISO file.
  4. Create a Bootable Flash Drive:
    • To create a bootable flash drive, you need to write the bootable image onto the drive. Several software tools can help you with this, including:
      • Rufus (for Windows): Download and install Rufus. Open the software, select your USB drive, browse for the bootable image, and click “Start” to create the bootable drive.
      • Etcher (cross-platform): Download and install Etcher. Open the software, select the image file, choose your USB drive, and click “Flash” to create the bootable drive.
      • UNetbootin (cross-platform): Download and install UNetbootin. Open the software, select the image file, choose your USB drive, and click “OK” to create the bootable drive.
  5. Access BIOS/UEFI Settings:
    • To boot from the flash drive, you need to configure your computer’s BIOS or UEFI settings. Restart your computer and access the BIOS/UEFI by pressing a specific key during startup. The key to access these settings varies depending on your computer’s make and model (common keys include Del, F2, F12, or Esc). Consult your computer’s manual or the startup screen for the correct key.
  6. Change Boot Order:
    • Once you’re in the BIOS/UEFI settings, navigate to the “Boot” or “Boot Order” section. Change the boot order to make the USB drive the first boot device. Save your changes and exit the BIOS/UEFI settings.
  7. Boot from USB:
    • With the flash drive inserted and the boot order set, restart your computer. The computer should boot from the flash drive. You might be presented with a boot menu where you can select the USB drive as the boot device.
  8. Follow the Installation or Usage Instructions:
    • Depending on the bootable image’s purpose (e.g., OS installation or running a live environment), follow the on-screen instructions provided by the image. If you’re installing an OS, you’ll go through the installation process just as if you were using a CD or DVD.
  9. Eject the Flash Drive (if necessary):
    • After you’ve finished using the bootable image, make sure to safely eject or remove the flash drive.

The specific steps and options may vary depending on your computer’s manufacturer and model, as well as the bootable image you’re using. Always refer to the official documentation for the operating system or tool and your computer’s manual for any unique instructions.
