How To Boot Operating System In Pendrive


Booting an operating system from a USB flash drive (pendrive) is a common practice, especially for tasks like installing a new operating system or running a live version of an OS. Here’s how to do it:

  1. Prepare the Pendrive:
    • 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 USB drive or back up any important data to another location, as the process will involve formatting the drive.
  3. Obtain the OS Image:
    • You’ll need the operating system image that you want to boot from. This is typically in the form of an ISO file. You can download OS images from official websites, such as Windows ISOs from Microsoft, Linux distributions from their respective websites, or other specialized OS images as needed.
  4. Create a Bootable USB Drive:
    • To create a bootable USB drive, you’ll need software that can write the OS image to the USB drive. Some popular tools for this purpose include:
      • Rufus (for Windows): Download and install Rufus. Open the software, select your USB drive, and browse for the OS image. Click “Start” to create the bootable drive.
      • Etcher (cross-platform): Download and install Etcher. Open the software, select the OS image, and the USB drive. Click “Flash” to create the bootable drive.
      • UNetbootin (cross-platform): Download and install UNetbootin. Open the software, select the OS image and USB drive, and click “OK” to create the bootable drive.
  5. Set BIOS/UEFI to Boot from USB:
    • To boot from the USB drive, you need to configure your computer’s BIOS or UEFI settings. Restart your computer and access the BIOS/UEFI settings by pressing a specific key during startup (usually Del, F2, F12, or Esc). Find the “Boot” or “Boot Order” section and set the USB drive as the first boot device. Save your changes and exit the BIOS/UEFI.
  6. Boot from USB:
    • With the USB drive inserted and the boot order set, restart your computer. It should boot from the USB drive. You may be presented with a boot menu where you can select the USB drive as the boot device.
  7. Follow the Installation/Usage Instructions:
    • Depending on your purpose (e.g., installing the OS or running a live environment), follow the on-screen instructions provided by the OS. For a typical OS installation, you’ll go through the installation process just as if you were using an optical disc.
  8. Remove USB Drive (if necessary):
    • After the OS is successfully installed or you’ve finished using the live environment, remove the USB drive. Make sure not to boot from it in the future unless you need to.

Remember that the specific steps can vary depending on the operating system you’re using and the make and model of your computer. Always refer to the official documentation for the operating system and your computer’s manual for any unique instructions.
