💾 How to Create a Bootable Pen Drive – Step by Step Guide
A bootable pen drive is a USB flash drive that contains all the necessary files to start or install an operating system (OS) on a computer. It is commonly used for installing Windows, Linux, or repairing systems without using a CD/DVD.
A bootable pen drive can save time, is portable, and works on computers without an optical drive.
Why You Might Need a Bootable Pen Drive
- Install or reinstall Windows or Linux
- Repair or troubleshoot a system that won’t boot
- Run antivirus or recovery tools
- Backup and recover important files
Requirements Before You Start
- A USB pen drive with at least 8GB storage
- ISO file of the operating system you want to install
- A Windows computer to create the bootable drive
- Rufus or other bootable USB creation software (official source)
Part 2: Methods to Create a Bootable Pen Drive
There are several ways to create a bootable pen drive. The two most common methods are using software like Rufus or via Command Prompt (without additional software). Both methods are effective; choose the one that suits you.
Method 1: Using Rufus (Recommended)
- Download Rufus from its official website (rufus.ie).
- Insert your USB pen drive into the computer.
- Open Rufus – it will automatically detect your USB drive.
- Under Boot selection, click Select and choose the ISO file of the OS.
- Keep the default Partition scheme (MBR or GPT) based on your computer’s BIOS/UEFI.
- Click Start → Confirm any warnings (data on USB will be erased).
- Wait until the process completes – your USB is now bootable.
Rufus is fast, reliable, and works with Windows, Linux, and other OS ISO files.
Method 2: Using Command Prompt (Without Software)
- Press Windows + R, type cmd, and press Enter.
- Type diskpart → press Enter.
- Type list disk → press Enter to see all drives.
- Identify your USB drive (example: Disk 1), then type select disk 1.
- Type the following commands one by one:
- clean
- create partition primary
- select partition 1
- active
- format fs=fat32 quick
- assign
- exit
- Copy all files from the OS ISO to the USB drive.
- Your USB is now bootable.
Part 3: How to Boot from the Pen Drive and Install Windows/Linux
After creating a bootable pen drive, the next step is to boot your computer from it and install the operating system. This process may vary slightly depending on your computer’s BIOS or UEFI settings.
Step 1: Insert the Bootable Pen Drive
- Turn off your computer.
- Insert the bootable USB drive into a USB port.
- Turn on the computer.
Step 2: Enter BIOS/UEFI
- Immediately press the key to enter BIOS/UEFI during startup (commonly F2, F10, DEL, or ESC).
- Navigate to the Boot menu.
- Set your USB drive as the first boot device.
- Save changes and exit BIOS (usually F10).
Step 3: Boot from USB
- Your computer will restart and boot from the USB pen drive.
- Follow the on-screen instructions to install your operating system.
- Choose language, time zone, and partition settings as required.
Step 4: Complete Installation
- Wait for the installation process to complete (may take 15–30 minutes depending on OS and system).
- Once done, remove the USB drive and restart your computer.
- Your new OS will load, and you can set up your accounts and preferences.
Always backup your important files before installing a new operating system, as installation may erase existing data.
