Using the diskpart tool in Windows 10 or Windows 11 to create a bootable USB is a slightly technical method, but it is very effective, especially when you need precise control over the partitioning and formatting process of the USB drive. Here is my experience sharing of using diskpart to convert Windows ISO to a bootable USB:

 

First, you need an empty USB drive with at least 8GB of space to ensure that there is enough space for the Windows installation files. Before you begin, insert the USB drive and make sure you save any important data on the drive, as this process will erase all data.

 

Open Command Prompt: Run Command Prompt with administrator privileges. Type "cmd" in the Windows search box, then right-click "Command Prompt" and select "Run as administrator".

Start the diskpart tool: Type diskpart in the command prompt and press Enter. This will start the diskpart tool.

 

Identify and select the USB drive:

Type list disk to see a list of all disks and find your USB drive (based on the size).
Select your USB drive using the select disk X command, where X is the number of your USB drive.


Prepare the USB drive:

  1. Type clean to clear all partitions on the USB drive.
  2. Type create partition primary to create a new primary partition.
  3. Type select partition 1 to select the partition you just created.
  4. Type active to mark the selected partition as active.
  5. Type format fs=ntfs quick to quickly format the file system to NTFS (FAT32 can also be used, depending on your needs).
  6. Type assign to assign a drive letter to the USB.

Copy the ISO file to the USB: After exiting diskpart, you need to extract and copy all the contents of the ISO file to the USB drive. This step can be done manually using File Explorer.

 

After completing these steps, your USB drive will be a bootable disk. You can use it to boot your computer and install Windows. Although this process is multi-step, you will have more control with diskpart, especially when dealing with different types of USB drives or troubleshooting boot problems.
