Before we get started, you will need a few things:

  1. Insert the USB drive into your computer’s USB port.
  2. Open “My Computer” or “This PC” and right-click on the USB drive.
  3. Select “Format” from the drop-down menu.
  4. In the format window, make sure the file system is set to “FAT32” and click “Start”.
  5. Once the format is complete, your USB drive is ready to be made bootable.

Step 2: Download and Install a Bootable USB Creation Tool

There are several free tools available online that can help you make your USB drive bootable. Some popular options include Rufus, UNetbootin, and WinToFlash. Choose the one that best suits your needs and download it onto your computer. Once downloaded, follow the installation instructions to install the tool.

Step 3: Create a Bootable USB Drive

Now it’s time to use the bootable USB creation tool to make your USB drive bootable. The steps may vary slightly depending on the tool you are using, but the general process is as follows:

  1. Open the bootable USB creation tool.
  2. Select the ISO file of the operating system or diagnostic tool you want to boot from.
  3. Choose the USB drive you want to make bootable.
  4. Click “Start” or “Create” to begin the process.
  5. Wait for the tool to finish creating the bootable USB drive.

Step 4: Test Your Bootable USB Drive

Once the bootable USB drive has been created, it’s time to test it out. To do this, follow these steps:

  1. Insert the bootable USB drive into the computer you want to boot from.
  2. Restart the computer and enter the BIOS or boot menu by pressing the designated key (usually F2, F10, or Esc) during startup.
  3. In the BIOS or boot menu, select the USB drive as the primary boot device.
  4. Save the changes and exit the BIOS or boot menu.
  5. The computer should now boot from the USB drive.


Making a USB pendrive bootable is a simple process that can come in handy in various situations. Whether you need to install a new operating system or run a diagnostic tool, having a bootable USB drive can save you time and hassle.
