The simplest method is to copy the DVD files or extract an official ISO. It is also possible to use the Microsoft Deployment Toolkit (MDT) to customize an image and deploy this via USB drive.

End users could use Windows 7 USB/DVD Download Tool. Please ensure that the USB flash drive has a minimum capacity of 4GB.

Basic Overview

  1. Using diskpart:
    1. Clean USB drive
    2. Create primary partition
    3. Format partition as NTFS
    4. Set partition as active
  2. Copy DVD files or extract official ISO onto the drive
  3. Boot PC from USB and install

Diskpart Commands

This process will prepare the USB drive for the Windows 7 disk files. In normal Windows GUI format tool, the Allocation Unit Size must be set to 4096 bytes. This works with some USB drives and fails in some USB drives. Therefore, diskpart is used.

Please note: This will delete all data on the drive, so ensure all files are backed up before continuing.

  1. Open the command prompt
  2. Type: diskpart
  3. Type: list disk
  4. This will show all connected disks, their disk numbers, connection status and disk size
  5. Using the sizes, determine which disk is your USB drive and remember its disk number (i.e. Disk 2)
  6. Type the following commands: (where X is the disk number of your USB drive)
    1. sel dis X
    2. clean
    3. cre par pri  
    4. active
    5. format fs=ntfs  Quick
    6. exit

Once the disk is formatted and prepared, you can copy the Windows 7 installation files onto the disk, whether this is from the DVD, ISO or a modified image.
