Part 1. Create bootable Windows installation USB media via CMD

First of all, we will show you how to create a bootable USB drive for installing the OS.

Tips:
● The USB drive should be at least 4GB of storage (for a 32-bit operating system) or at least 8GB (for a 64-bit system).
● Back up files you have stored on the USB drive because the drive will be formatted during this process and all files on it will be erased.

Step 1. Open Command Prompt windows: click “Start” button, input “cmd” in the Search box and press “Enter”. Right click the “Command Prompt” icon and select “Run as administrator”.

Step 2. In the pop-out Command Prompt window, type “diskpart” and press “Enter” to launch Diskpart utility. Inside the Diskpart window, input the following commands in turn and press “Enter” after each one.

  • list disk
  • select disk #
  • clean
  • create partition primary
  • select partition 1
  • format fs=ntfs quick (if you plan to create UEFI bootable USB using Diskpart, type “format fs=fat32 quick” instead to format it into FAT32 file system)
  • active
  • exit
Create Bootable USB CMD

Don’t close the Command Prompt. You can minimize it for a little bit since the process is not finished yet. Now, put the Windows DVD into your computer’s DVD drive. Open Windows File Explorer to check out the drive letter of the Windows DVD drive and the USB drive.

Then, go back to the CMD window and type in “D: CD BOOT” (replace D: with your DVD drive letter) and press Enter. Type “CD BOOT” again and press Enter. Lastly, type “BOOTSECT.EXE /NT60 H: “ (replace your USB flash drive letter for H:) and press Enter.

At last, copy all the files and folders of the Windows DVD to your USB flash drive in File Explorer. Now, you can plug the bootable USB flash drive into the target computer to start installing OS.
