Important Warning: This process will completely erase everything on your USB drive. Please back up any important files from the USB stick before you begin .

Preparation​

• USB Drive: At least 8GB in size .
• ISO File: The Windows ISO you want to use, already downloaded .
• Permissions: You must run Command Prompt as Administrator.

Step 1: Open Command Prompt as Admin​

1. Press the Windows Key + R on your keyboard.
2. Type cmd and press Enter.
3. Right-click on "Command Prompt" in the results and select Run as administrator .

Step 2: Prepare the USB with DiskPart​

In the Command Prompt window, type the following commands in order, pressing Enter after each line :

1. diskpart (Starts the disk partitioning utility)
2. list disk (This shows all disks connected to your PC. Identify your USB drive by its size.)
3. select disk # (Replace # with the number of your USB drive. For example, if it's Disk 1, type select disk 1.) This is the most critical step—make sure you select the correct disk .
4. clean (Wipes all data from the selected USB drive) .
5. create partition primary (Creates a new primary partition) .
6. select partition 1 (Selects the newly created partition) .
7. active (Marks the partition as active so the system can boot from it) .
8. format fs=ntfs quick (Formats the drive quickly with NTFS. For UEFI boot, you can use fs=fat32 instead) .
9. assign (Assigns a drive letter to the USB) .
10. exit (Exits DiskPart) .

Step 3: Copy Installation Files​

1. Locate the Windows ISO file you downloaded. Right-click it and select Mount (Windows 10/11) or Open with > Windows Explorer .
2. Open a new File Explorer window and navigate to your USB drive.
3. Select all files and folders from the mounted ISO drive and copy them to the USB drive .

Once the copying is complete, your bootable Windows USB is ready. You can now use it to boot and install Windows on a PC.

Enjoy!
