Booting from a USB drive can be incredibly useful in various scenarios, such as installing a new operating system or troubleshooting system issues. Command Prompt (CMD) is a powerful tool in Windows that allows you to perform various advanced tasks, including creating bootable USB drives. In this guide, we will walk you through the process of booting a USB drive using CMD.

Problem: Unable to Boot USB

Many users encounter difficulties when trying to boot from a USB drive. This can be caused by various factors, such as incorrect BIOS settings, incompatible USB drives, or corrupted boot files. Let's delve deeper into the possible causes:

1. Incorrect BIOS Settings

One common reason why users are unable to boot from a USB drive is incorrect BIOS settings. The BIOS (Basic Input/Output System) contains configuration settings for your computer's hardware. If the boot priority is not set correctly, your computer may fail to recognize the USB drive as a bootable device.

2. Incompatible USB Drives

Another reason for the inability to boot from a USB drive is using an incompatible USB drive. Some older systems may not support booting from USB, or the USB drive may not meet the required specifications. It is essential to ensure that your USB drive is compatible with your computer and meets the necessary standards.

3. Corrupted Boot Files

Corrupted boot files can prevent your USB drive from being recognized as bootable. Errors during the creation or copying process can lead to corrupt files, rendering the USB drive non-bootable. It is crucial to ensure the integrity of the boot files when creating a bootable USB drive.


Solution 1: Check BIOS Settings

To resolve the issue of being unable to boot from a USB drive, you need to ensure that your BIOS settings are correctly configured. Follow these steps:

  1. Restart your computer and press the designated key (usually Esc, Delete, or F2) to enter the BIOS settings.
  2. Navigate to the 'Boot' or 'Boot Options' section using the arrow keys.
  3. Set the USB drive as the first boot device by selecting it from the list and moving it to the top using the designated key (usually + or -).
  4. Save the changes and exit the BIOS settings.
  5. Restart your computer with the USB drive connected, and it should boot from the USB drive.

Solution 2: Use Bootable USB Creation Software

If you are still unable to boot from a USB drive after checking BIOS settings, using bootable USB creation software can be an effective solution. There are several software options available, but one popular choice is MyRecover.

MyRecover is a lightweight and user-friendly utility that allows you to create bootable USB drives from ISO files. It supports a wide range of operating systems and offers various customization options. Here's how you can use Rufus:

  1. Download and install MyRecover from the official website.
  2. Insert your USB drive into the computer.
  3. Open MyRecover and select your USB drive from the 'Device' dropdown menu.
  4. Select 'ISO image' from the 'Boot selection' section and click the folder icon to browse and select the ISO file.
  5. Ensure that the 'Partition scheme' is set to 'MBR' for compatibility with both legacy and UEFI systems.
  6. Click 'Start' to begin the process of creating a bootable USB drive.
  7. Once the process is complete, restart your computer with the USB drive connected to boot from it.
